Crash when Nvidia shader cache is enabled

[Irityan]

See more details here.
Unless nvidia's shader cache is disabled, all emulators that use the latest version of parallel-rdp will crash after some time after booting any game.

Happens on both simple64 and ares when using the latest version of those emulators. (in contrast, version v138 of the ares emulator works as intended)

Disabling the shader cache seems to fix the issue.

(UPD. If that helps, the GPU I'm using is Nvidia GeForce GT 1030)

A little bit more context: version v138 of the ares emulator uses the commit afc61e1 of parallel-rdp. Version v139 uses 2549779.

Update: Somehow I got the used commit for v139 wrong ... it uses the latest version of parallel-rdp.

Update: I try to bisect Granite.

Seeing how the issue not reported by anyone else, could the problem be with specific older GPUs?

Mine is GeForce GT 1030.

Maybe some update uses a feature (related to shader cache) that is not implemented for older hardware? If it's that, then I guess there is nothing that can be done, really. But again, I'm just merely a user and not a graphics programmer or anything.

I was able to bisect the responsible commit in the Granite repository: Themaister/Granite@1faa401

Indeed, it disables some workarounds for NVIDIA cards with driver versions >= 535. These workarounds seem to be needed in our case, so this condition is probably too restrictive. I removed that condition and compiled the latest Granite with the latest parallel-rdp and ares version v139. This resolves the issue.

Because the issue is actually in Granite and not in parallel-rdp, we should probably open an issue on the https://github.com/Themaister/Granite repository instead.

iirc, this only reproduced on Pascal and older cards.

Seems to be fixed with your latest update to Granite and parallel-rdp.
