[Bug] Black borders in editor and stretching in shipping build

I have a weird bug in the editor where part of the screen goes black and starts blinking. The problem occurs on different maps and machines.

Also sometimes there is a strange frame stretching on shipping build, quite similar to the problem in the editor:

Maybe someone has encountered this and knows how to fix it?

Hey there @Dangetsu-PK! Are you by chance using the DLSS plugin? There was an update recently that caused this issue for some users, and was corrected in a patch that followed (in 5.4).

I do use DLSS, but I’m already sitting on the latest 5.4.4 patch as it is. Also, I tried turning off those plugins, but that didn’t help.
The only thing that helped was turning on hardware lumen. But for technical reasons I can’t use it in shipping build.

Turning on Hardware Raytracing corrects the problem? Interesting! Are you using any other upscaling/sampler plugins?
