vulkan: Flickering/Corrupt/Swapped Textures on Intel drivers

[retroNUC]

Summary

Textures in the game appear to be flickering/corrupt/swapped when being encountered for the first time on Vulkan. Most obvious on the title screens. Default settings, only just started using RPCS3. Game rendering fine when using OpenGL.

Lol, the classic event sync bug on AMD proprietary. Needs KHR_synchronization2 but we also have an in-place workaround for AMD that should resolve this one as well.

Should be fixed by https://github.com/RPCS3/rpcs3/pull/12072. Please verify as I do not have the required hardware.

Tested on 0.0.22-13643 with included change. While the majority of texture corruption appears to be gone with this fix, especially with flickering on moving/animated sprites, some texture corruption and disappearing sprites still remain on Vulkan that do not occur on OpenGL.

Reopening. Needs synchronization2 extensions to fix it properly.

Should be fixed by https://github.com/RPCS3/rpcs3/pull/14065 assuming no driver bugs on intel.

Unfortunately, issue is still occurring in latest nightly RPCS3 build (0.0.28-15229), with latest Intel drivers (101.4502). New logs/capture attached.

Try with https://github.com/RPCS3/rpcs3/pull/14101. Each driver and hardware seems to expect different setups and I just don't have Xe on hand.

Try with #14101. Each driver and hardware seems to expect different setups and I just don't have Xe on hand.

I can't reproduce this one, either in the Master or in the specified PR. The game runs perfectly here.

Corruption still occurs on my system in 0.0.28-15270, which includes the above PR.

Less corruption (not seeing on the big Majesco logo any more), but still on many other texture elements during the intro.

Just to double-check, I reproduced this on a completely fresh install of RPCS3.

Reopening. However, we don't have access to any xe hardware, so I'll remove from my wq for now.

For clarification, I'm not running any dedicated Xe/Arc hardware, this is just Intel integrated graphics on an 11th Gen CPU (Core i7-1165G7).

They stopped calling their integrated graphics 'Xe' after this very small period so it wouldn't confuse people with their upcoming dedicated hardware and went back to the 'UHD' moniker for 12/13th Gen, but I imagine you may be able to reproduce this on any modern (11th Gen onwards, non-F/KF) Intel CPU with any extra GPU hardware disabled.
