Wine 11.12 deadlocks Affinity renderer on Intel Arc (works on 11.0)

[jfacemyer]

Installed via AffinityOnLinux. After updating Wine 11.0 → 11.12, Affinity's UI loads but opening a document hangs — canvas never renders, no crash. 11.0 works perfectly; 11.12 and 11.12v4 both hang.

System: Intel Arc A750 (Mesa 26.1.4, Vulkan 1.4) · Ryzen 9 3950X · Manjaro, kernel 7.1.3 · Wayland/Xwayland · Affinity 3.2.3.4646 · ElementalWarrior wine-11.12.

winedbg backtrace — hung thread is Affinity's renderer stuck in a Win32 wait that never returns:
ntdll (wait) ← kernelbase!WaitForMultipleObjects ← libkernel ← libraster ← librenderer
No vkd3d/dxgi/vulkan/d3d frames anywhere — it's a lost wakeup on a Win32 event, not a GPU call.

Ruled out (all still hang on 11.12): vkd3d/Vulkan/GPU driver · OpenCL disabled · all sync backends (fsync, server-side, ntsync w/ /dev/ntsync) · both display drivers (X11 + Wayland) · 11.12v4.

Key clue: forcing software Vulkan (lavapipe), so the Arc is bypassed, makes it intermittent — renders on some launches, hangs on others. On the real Arc driver it hangs almost every time. Looks like a timing-dependent lost-wakeup introduced in 11.12, where the fast hardware path loses the race and the slow software path sometimes wins.

Q: Anyone on Arc/Mesa ANV seeing 11.12 hang where 11.0 works? Known Wine 11.x change (event signaling / scheduler) that could cause this? Full logs + winedbg dump available.

same problem with my amd rdna2, i have to use Wine EW-10.10

EW-11.0 works too

Same here on my AMD Ryzen AI 7 PRO 350, Zorin 18.1. Tried the AMD and normal build of 11.12, but both hung. EW-10.10 works so that's what I'm currently using.
