Hello radeonsi / RADV ACO fellows,
found the solution for the below Qt 6.9.0 (maybe former) AMD radeonsi
(Vulkan/RADV) rendering issue.
ACO is the culprit (for radeonsi at least).
AMD_DEBUG=usellvm SOLVED it on my side.
Have to open a Ticket on gitlab.
Greetings,
Dieter

(For me) It is an
Mesa git radeonsi (amdgpu) ACO driver bug.
When I disable ACO (AMD_DEBUG=usellvm)
Issue is SOLVED.
