Description Oleg 2020-08-12 15:08:46 UTC
This problem has existed for many months already. While I am on the console (x11 or wayland are not loaded), 8 BSD logos sometimes appear in the left corner of my screen. The problem can be seen in the attachment provided. I use drm-devel-kmod/i915kms. I am running FreeBSD 13.0-CURRENT r364115, but as I said, this problem has existed for many months already.

This seems like it might be a bug in VT splash CPUs; as a workaround, the (non-default) splash cpus can be disabled by removing kern.vt.splash_cpu from loader.conf and sysctl.conf, or by setting a zero value.
Comment 4 Ed Maste freebsd_committer 2020-08-19 14:25:31 UTC
While investigating PR 211922 I observed orb logos, despite kern.vt.splash_cpu=0.
Comment 5 Rajeev Pillai 2020-10-19 07:54:11 UTC
I'm seeing this in FreeBSD 12.2-RC3 amd64 also. It is extremely reproducible:

1. In the framebuffer console run yes(1).
2. Left-click and drag the mouse.
3. Switch to another console.

The orb logos (4, equalling the no. of CPUs) appear at the top-left corner
and then the mouse pointer cannot be brought to the bottom of the screen
anymore. It stops at what looks like (fb_height - orb_logo_height) of the
screen.

This patch seemed to fix it for me:

It doesn't fix the issue for me.

That patch doesn't work for me either on FreeBSD 12.2-RELEASE with efifb.

Setting "kern.vt.splash_cpu" to 0 only changes the content of the image. On FreeBSD 12-STABLE, that changed red head orbs to sitting penguins.
