Dear Maintainer,
When I start for instance Neverball on Xmonad and either:
* set it to fullscreen with, vsync=off or
* set it to windowed but resize it / show it fullscreen via the Xmonad
fullscreen layout
Then I get the following issue:
* The start screen with its 3D animated background is only
rendering/refreshing if I move the mouse pointer and then only the
few vertical lines around this mouse pointer. I can switch to
another TTY and back to the Xmonad TTY, but if I do this a few
times then the system hangs completely.
If I either enable VSync for Neverball or if Neverball is not occupying
the full screen then I don't get any rendering issues.
I could reproduce the issue with the following window managers which
I selected from the LightDM login greeter:
* Xmonad, i3, dwm, Gnome (with X11), Mate with "xmonad --replace"
I could not reproduce the issue with the following window managers:
* Gnome (Wayland) or Mate (as is, without "xmonad --replace")
Applications I could reproduce it with:
* Neverball, Warzone2100 (with all 3 gfxbackend options:
opengl, opengles, vulkan), 0ad
Tested on latest Debian Sid, Linux 6.1.4-1. Firmwares should be up to date,
updated EFI/system firmwares via fwupdmgr and installed the latest
firmware-amd-graphics package from non-free (20221214-3). There is no
later Yellow-dog firmware for firmware-amd-graphics in its Git
repository.
I'm hoping this is the right Debian package to report this to (or should
this better be the firmware-amd-graphics package?).
Cheers, Linus
