Fossilize

I had that with MHW and I nailed it down to shader (fossilize-replay - https://github.com/ValveSoftware/Fossilize). From my guess, Steam support Vulkan shader pre-compilation so that you don't have to wait in game (like the infamous 10 min Monster Hunter Wilds startup delay). They also seems to also be able to download the compilation cache from Steam if someone already have done the process on the same GPU + driver version. Since fewer Windows games use Vulkan this feature is often not used, but on Linux most games will run on Vulkan (esp. Proton games with dxvk) you may experience the process more often.

It could be revived via "fossilizing"[1] vulkan commands made possible by valve. Maybe even as a Wayland extension. [1]:https://github.com/ValveSoftware/Fossilize

So far my version is just a crudely hacked together proof of concept on top of st I did as hobby. It just renders textured polygons without any shaders or more advanced stuff. Since this is my first OpenGL application ever it probably won't ever be released to the public. Somebody else with more experience should rather do it. A More advanced protocol like Valves Fossilize (https://github.com/ValveSoftware/Fossilize) should be used for that which means I can throw away my code anyways at this point. However serialized graphics does not seem a project goal of either kitty or alacritty.
