So, this might be due to differing radeon_surface layouts based on the RADEON_SURF_SCANOUT flag.
tvoss can apparently reproduce this, and it goes away when he *doesn't* add the SCANOUT flag to the gbm bo in Mir¹. XMir never sets RADEON_SURF_SCANOUT, so it's plausible that this is the issue. ¹: Luckily, it appears that this buffer still happens to be scanoutable ☺ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1218815 Title: [radeon] Graphic glitches and screen corruption (vertical lines) on XMir surfaces only Status in Mir: Triaged Status in XMir: Triaged Status in “xorg-server” package in Ubuntu: Triaged Status in “xserver-xorg-video-ati” package in Ubuntu: Triaged Bug description: Since the latest Ubuntu Mir update which enabled the bypass support I get heavy graphic glitches when using the unity-system-compositor.
