Bug ID: 111400
Summary: Prime offloading to iGPU leads to highly stretched
window content
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/Iris
Assignee: intel-3d-bugs at lists.freedesktop.org
Reporter: tempel.julian at gmail.com
QA Contact: intel-3d-bugs at lists.freedesktop.org
When I run "MESA_LOADER_DRIVER_OVERRIDE=iris DRI_PRIME=1 glxgears", the window
content is highly stretched and thus looks garbled. This doesn't happen with
some window sizes or aspect ratios though, and neither happens in maximized
window or fullscreen mode.
The display has typical 16:9 AR and 1440p resolution, it's connected to a RX
570 card using amdgpu driver (and xf86-video-amdgpu).
Tested with latest xorg-git and mesa-aco-git with
commit32cd9487f45372e0677603218a586ea99296d1d3. Happens with both
xf86-video-intel and modesetting.
