Bug 235195

Created attachment 201392 [details]
List of installed ports on 19/01/19, after upgrade.

Continuing my previous submission.

When I initially log in, some strange behavior occurs.  For example, using firefox, when the bookmarks button is clicked, nothing appears until after the mouse is moved down, at which point only the icons on the left of the menu show up.  The rest of the menu items only appear as the mouse is moved down over them.  Generally, firefox then goes to the selected web pages, but it is not long until menus only appear as black and the main window ends up black as well.

Some History:

I reinstalled all my ports a few weeks ago so as to start using kde5.  I have attached the output of "pkg version" both before, upgrade-a-19012.ver, and after, upgrade-a190119.ver, the offending upgrade. Looking in the svn repository, I see plasma5 was updated, r490472, between these two upgrades of the ports tree.

Later I upgraded the OS after a security email.  The output "uname -a" is:

FreeBSD hydrogen 11.2-RELEASE-p8 FreeBSD 11.2-RELEASE-p8 #0 r343007: Mon Jan 14 17:07:39 AEDT 2019     root@hydrogen:/usr/obj/usr/src/sys/GENERIC  amd64

I login from sddm.

I set up an new user account with no files and logged in to it.  The same behavior occurred.  So it is not my personal set-up that causes the problem.

I have also tried rebuilding everything. Again, this failed to fix the problem.

./local/share/sddm/xorg-session.log for the initially empty guest account.

Have attached .local/share/sddm/xorg-session.log for a session using the initially empty guest account.

Note, the messages near the end, starting from:
"Unexpected response from KInit (response = 34417092560).
startkde: Could not start ksmserver. Check your installation."
are a result of manually killing the running kdeinit5 process to escape back to the login prompt.

System Settings ▶ Display and Monitor ▶ Compositor

Which rendering backend is preferred?

Also: 

pciconf -lv | grep -B 3 -A 1 display

kldstat

"System Settings ▶ Display and Monitor ▶ Compositor" shows
"OpenGL 2.0" as the "Rendering backend".

Also,
"compositing on startup" is enabled, the "Animation speed" is set to halfway between "Instant" and "Very slow", the "Scale method" is "Accurate", "Tearing prevention("vsync")" is "Automatic", "Keep window thumbnails" is "Only for Shown Windows" and "Allow applications to block compositing" is enabled.

Note, these were all automatically set.  I haven't changed any of them.

Here is a description of more observed behaviour which has no dependency non-KDE applications, except that applications have been automatically found and inserted into the application menus.

I created a test account with no configuration files.  I then logged in from sddm. Then I opened a Konsole window via Applications>System>Terminal.

One peculiar behaviour is the when I try to move a window into the bottom right-hand corner, it seems to hit an obstacle and starts to reduce in size.  Also, the redrawing stops working properly, so that there are partial redraws of the window as I move it around, without erasures of previously drawn fragments.  Everything returns to normal once I move the window away from the forbidden region.

Note, there is no problem moving the window left-to-right or top-to-bottom, provided the window doesn't encroach into the region near the bottom right-hand corner.

It is difficult to determine the exact size of this forbidden region, but it seems to be the same size as a small message window, there is nothing to indicate there is anything there.

After closing and creating a number of Konsole windows, an instance appears where only the title bar and frame is visible, the body of the window being transparent.  At this point, kde menus become transparent, and hence unusable, with only the shading of their frame visible.  I then have to kill the running Kdeinit process manually from the console.  A message window, with its body blacked out, appears on the kde desktop.  On closing this window, the desktop session closes and the sddm welcome screen appears.  After which I can log in again.

Are you using x11/nvidia-driver?


Mfg Tobias

My bad.

I was not using any nvidia drivers.  I've just installed them and everythings behaving fine now.  At least so far.

However, that doesn't explain why I started having problems after updating everything on 18/01/19.

Note, I did consider the possibility that things were very slow, but it seemed no longer how long I waited for the desktop menus to be filled in, nothing happened.  They stayed stubbornly transparent.

Comment 8 Jan Beich 2019-02-03 12:32:44 UTC

IIRC, xf86-video-scfb and xf86-video-vesa use software rendering by default: llvmpipe from mesa-dri. Recent mesa-dri 18.1.9 -> 18.3.2 could regress llvmpipe. Try rolling back to 18.2.8, then 18.1.9.

As stated in my previous comment (2019-02-03 09:52:33 UTC), installing the nvidia driver fixed the problem.

Nevertheless, to help identify what caused it in the first place I started the regression of mesa-dri, as suggested by Jan Beich (2019-02-03 12:32:44 UTC).

The first step was to delete the nvidia packages I had installed, i.e. nvidia-driver-340-340.107_3, nvidia-settings-415.25 and nvidia-xconfig-415.25.  I rebooted and then checked to see if the problem had returned.  To my surprise, everything seemed to work as it should.  Application menus worked normally.  The strange forbidden region of the screen (see my comment 2019-02-03 03:25:47 UTC) didn't manifest itself.

To see if I could recreate the problem, I then removed the linux compatibility packages installed when I installed the nvidia driver, i.e. linux-c6-expat-2.0.1_5, linux-c6-fontconfig-2.8.0_3, linux-c6-xorg-libs-7.4_10 and linux_base-c6-6.10.  Again, I rebooted to see if the problem had returned.  Again, everything was, and still is, working normally.  Note, these were the only linux compatibility packages on my system.

As a result, I'd like to know if there is still any point in regressing mesa-dri as suggested by Jan Beich?  I'm actually not sure if I can perform this regression.

FYI, I have included a list of all the upgrades I have done since this problem appeared.  None of them in themselves fixed the problem, but they may have some bearing on why it has not reappeared.

I don't think there's much kde@ can do here. This is more up the xorg/drm-driver people's alley.


Is it still an issue though?


mfg Tobias

As I noted in my comment 2019-02-05 01:03:48 UTC, after deinstalling the nVidia driver, the problem did not reoccur, so I don't think it was a problem with the nVidia driver, which was not installed when the problem first appeared.

It seems, something funny happened when I did the update on 18/01/2019 and installing and deinstalling the nVidia driver fixed it.  Presumably, installing the nVidia driver installed something or changed some setting which persisted even after the nVidia driver was deinstalled.  Is this a clue to what was going on?

Unfortunately, without being able to recreate the problem, there doesn't seem to be any way to determine what caused it.

To answer your question, it probably isn't an issue any more.  At least until it bites some one else:)

I've same problem.

Configuration:
FreeBSD as virtual machine in Virtualbox.
root@bsd12:~ # uname -a
FreeBSD bsd12 12.0-RELEASE-p4 FreeBSD 12.0-RELEASE-p4 GENERIC  amd64

The same problems have been detected on physical HW with Radeon graphics card.

True, happens only if using OpenGL 3.1 or 2.0, with Xrender it works fine:

pciconf -lv
vgapci1@pci0:0:2:0:     class=0x030000 card=0x06e51028 chip=0x191b8086 rev=0x06 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'HD Graphics 530'
    class      = display
    subclass   = VGA

Looks more like a X problem.

I can confirm problems with KDE5 Plasma on Radeon Vega 64 using amdgpu driver (12-RELEASE and generic kernel).

The issue isn't exactly as described here, but the solution proposed in the preceding much alleviated the issue.

In my case the issue was lack of responsiveness from all UI elements. For example, when opening menu it looked as if the menu froze for a split of a second then, redraw part of it, then froze again, then redraw, etc.

When watching Youtube videos on Firefox the video would play for a few seconds, they stop for 1 second or so, then play again, then stop, and so on.

When moving windows around quickly they would froze in place then move again (dragging would probably be a good description).

I disabled the compositor as suggested in the comment and now the UI is much much more responsive. Still not as responsive as when using NVidia driver (I have another system with NVidia card so can compare) but I would assume it could be due to the immature amdgpu driver. For example, the video on Youtube may still freeze but for much shorter (split of a second) much less often (say after 20 seconds of playing).

Has there been any changes with the recent upgrades of Plasma Desktop? 
Maybe this should be moved to the amd-driver maintainers.
