I have the option "Allow background processing of Vulkan shaders enabled" and I have several games installed, including A Hat in Time".
There's seems to be no indicator right now on the Steam UI that it's doing shader processing (there was one before the rollout of the new UI, I didn't find it after the redesign), but I can know due to the fan of the laptop speeding up.

The problem seems to be that the A Hat in Time shader compiling never finishes, I know it's stuck in the A Hat In time compiling because by checking htop fossilize_replay is working on the Steam app with the id of 253230 (which is A Hat in Time), also if I manually try to load A Hat in Time, but the compilation at that point also takes a long time, so I given up.
Letting the computer go 3 hours straight doing not more then shader compiling seems to not help, as apaprently it still doesn't do much progress.

Also, it seems sometimes the fossilize_replay can be crash, such as this:

Steps for reproducing this issue:

1. Enable "Allow background processing of Vulkan shaders" feature
2. Install A Hat In Time
3. Check if it properly compiles A Hat In Time shaders

Hello @MateusRodCosta, since this issue report focuses on the behavior of fossilize, I've transferred it to the fossilize issue tracker.

Can you check if (Steam install folder)/logs/shader_log.txt has any hints related to 253230 (A Hat in Time's appid)? already shared

Skimming over shader_log.txt and shader_log.previous.txt, I'm not seeing anything critically unusual.

Maybe it's hitting something in the Flatpak sandbox?

I have also these two from yesterday in ABRT in case it's any useful:

Maybe related to #211 or #117?

Just re-tried letting shaders compile in the background and it seems it succeded for A Hat in Time and a few other games without crashing.

It might have been fixed due to any update (I believe at least the Nvidia driver updated).

I will close this and if it re-appears I will reopen.

I will also try to open a new issue about the fact that there's no indicator that shaders are compiling on the new UI. Seems it already exists as ValveSoftware/steam-for-linux#9405.

Reopening.
It seems the problem is not so much the fact that the shader compilation never completes... (I actually let all games have their shaders processed a while ago)
The problems seems to be that on every new Steam launch it will want to check the compiled shaders and for the same few games it wants to do the processing all over again.

From the logs the games that it seems to happen the most (and it's the most noticeable because they have the most shaders) are:

• A Hat in Time
• Skyrim: Special Edition
• Dragon's Dogma: Dark Arisen

This is a bit annoying, because if I decide to play, say, A Hat in Time, I have to wait for hours for the shader processing again, which is kinda the reason I enabled background processing, to avoid waiting so much.

Attached new logs:

shader_log.txt
shader_log.previous.txt

This also happens on AMD Radeon RX 6600 (navi23, LLVM 15.0.7, DRM 3.49, 6.2.0-27-generic) (0x73ff) using Kubuntu 04/23. Steam installed via Flatpak.

I haven't tried to let it finish, I just click skip to get to play the game within a reasonable time.
