PCIE65 issue - any development happened?

I wonder did anyone spent some time on finding out where exactly problem is with pcie65 stuff.

GTK based apps have so many artifacts on text, that sometimes it is hard to read at all.

Qt/KDE ones display without any issues…

MPV (movie player) also shows text properly:

Also note that problem does not happen when llvmpipe is used instead of accelerated Mesa.

With llvmpipe, are you using the efi framebuffer or amdgpu drm kernel driver?

llvmpipe jumps in when system has both ASPEED and Radeon graphics cards.

Nevermind is ASPEED as astdrmfb or as simple-framebuffer.

Do you mean the PCIe-65 erratum for Altra family discussed in this github?

Yes. That.

My machine has WX2100 and RX6700XT in slots. Booting without pcie-65 patches is waste of time as system misbehaves when sddm starts.

Well I suppose if the GPU drivers were rewritten to ensure aligned accesses and not assume X86 style write combining, the kernel patches wouldn’t be necessary. I assume the nvidia gpu drivers are written in such a way.
