YES - OVER HERE! Same issue. it started with the last version of 5.3. Its not consistent and pretty glitchy. My workaround is to turn off and on the lights in my scene and at some point it suddendly works and keeps working.
I’m glad you posted it, I also was about to.
I have this issue on multiple systems and various GPUs. issues on 3090 and 4090. I switched GPU drivers around but there was no noticeble change. Keep running on the latest studio driver now.
Btw, it does not appear on MRQ renderings, its just in the editor.
When I have time I can exercise my newly learned skills in GPU debugging, but that could take some days as my schedule is absolutely full.
