With the latest blendluxcore daily version when i render in the viewport and then terminate the render view the cpu usage gets stuck at 100%.
My system win 10, blender 2.91.2, nvidia gpu.

Blend file to reproduce the issue
Re: Viewport render issue
I have also encountered this, but didn't find a way to reproduce it reliably yet.
Re: Viewport render issue
I also cannot reproduce it now.
I did a windows update, i don't know if that counts for something.

Re: Viewport render issue
Same here. Can't reliably reproduce it, but sometimes either memory leaks or it just crashes when I change a setting in an Image pipeline.
I only found a way to prevent it, while working long hours - turn interactivity off more often.
I was thinking of having an experimental time bomb switch to kill it after a a while of non-stop working with it. Something alike an old GPU "watch-dog".
But as I'm ignorant with coding, I can only do it manually.

Sometimes getting slow, sometimes crash and other times noting happen. But the only way to be sure I'm working without issues is to turn off interactive every a few changes so be sure the memory will be released.
I think because of caching the maps while changing gamma and other stuff that will cause memory leak somehow.
It will only happen on GPU, many times it's ok but it will happen occasionally. 6700k

I already report the issue on github too.

Re: Viewport render issue
The problem mentioned in the OP and experienced by me does not involve any crashes.
So KintuX and TAO, you might be describing different issues.

Re: Viewport render issue
I apologize for polluting the thread.
Indeed, it's a different issue than what's being described here (CPU usage stuck @ 100% when terminating viewport). It happened recently, but I 'killed' a process and can't reproduce it. Will try to keep it in mind and pay more attention in future.
Re: Viewport render issue
I managed to reproduce the problem, it happens when i hit z choose material preview then choose rendered viewport and finally choose solid viewport, the cpu usage remains at 100%.
Re: Viewport render issue
Nice, I tested it 3 times and it has reproduced the issue each time. Thanks, that helps a lot.
