--- Comment #1 from Alex Deucher (alexdeucher@gmail.com) --- This is a mesa bug. I'd suggest filing a bug here: https://gitlab.freedesktop.org/groups/mesa/-/issues There is either a memory alignment bug in the r600 mesa driver or the intel mesa driver is not allocating memory with the proper alignment requirements for the radeon hardware so when the radeon driver tries to use the buffer the commands get rejected causing the image distortions.
