Description Alexander Vereeken freebsd_triage 2021-02-16 21:58:53 UTC 
Hello,

when i start cinnamon start normally then i see the desktop but freezes directly. 

But when i start cinnamon with software renderer then it works.

With the normal gnome desktop this seems to be the same case.

GPU: AMD Radeon RX 570 using drm-kmod from ports with FreeBSD 12.2-STABLE r369250
Comment 1 Patricio Villar 2021-02-20 02:24:29 UTC 
Hi, I also had that issue with Intel HD 5500 graphics with drm-fbsd13-kmod and modesetting driver.
However, installing the (supposedly deprecated?) xf86-video-intel driver solved the problem...
Not sure about your AMD graphics though :(
Comment 2 Charlie Li freebsd_committer freebsd_triage 2021-02-20 04:36:51 UTC 
The issue with Intel modesetting is caused by something in the iris DRI/Gallium driver not agreeing with our graphics subsystem. xf86-video-intel is also affected if iris is used. See bug 251836.

Unfortunately, not sure about the AMD graphics issue, as I don't have any AMD graphics hardware.

glx_disable_ext_buffer_age

Disable buffer_age for x11/cinnamon on iris. This is a follow-up to bug 251836 that I forgot to add to the original Cinnamon update.

Note that this does not fix the original issue reported, which happens on AMD graphics hardware.

Its a x11-wm/mutter issue. Because i can reproduce the problem when using mutter standalone.

PR 253746 have been created for that issue.

How to close this issue correctly?

Cinnamon doesn't use Mutter. Further, Muffin, which forked from Mutter, is only linked and not ran directly. Thus, fixes on Mutter will need ported here, to x11/cinnamon, as well.
