I've got an OLAND era radeon card, and I'm using mesa-git. I can confirm the
issue exists using both the radeonsi and amdgpu kernel drivers. I'm using the
latest SVN revision for dosbox.
Using these config options:
[sdl]
fullresolution=desktop
output=opengl
[render]
aspect=true
which should maintain the desktop's display mode, use opengl for the output and
scale it to fit the screen while maintaining the correct aspect ratio.
Using these options, there are flashing artefacts outside of where the
application is rendering on my hardware. The artefacts are sometimes complete
garbage and other times they are noticeably the garbled remnants of a
previously opened application (for example, a youtube video or a previously
opened dosbox game).
The issue is far more pronounced on Xorg. Using wayland, I do occasionally get
a 1-pixel-wide line at the edge of dosbox's framebuffer, but it isn't flashing.
It's also unlikely to be an issue with Mutter, because I've tested it out in
openbox and got the same problem. IRC said it was most likely an issue on
mesa's end.
