Bug ID: 98993 Summary: dosbox artefacts when using opengl Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel at lists.freedesktop.org Reporter: aaronbpaden at gmail.com QA Contact: dri-devel at lists.freedesktop.org Created attachment 128338 --> https://bugs.freedesktop.org/attachment.cgi?id=128338&action=edit example image 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. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
