After updating CachyOS-Proton to version 20260506 today, I experienced a blackscreen with all UI elements being perfectly visible, as shown on the attached screenshots. It works fine when launching without Heap args.

Try latest Vulkan beta, not stable driver. Black screen with heap should be resolved there.
