After updating to the latest CachyOS-Proton version 11.0-20260506, the UI is flickering when Heap arguments are enabled and with them disabled the game runs fine.

Try again. Pushed a fix that would cause issues on RDNA2.

Unfortunately the issue is still happening.

I believe I did everything correctly, I followed the build instructions got the dll's and overwrote the proton version ones.
I also built the dll's from the descriptor-heap-rebase branch still no luck.

Also both branch dll's say they are applicationVersion: 3.0.1 and build: 6affb56f515a700.
So maybe I am doing something wrong.

Thank you for looking at this and you help is much appreciated.
