PS transform/zoom stops working after 20mins or so
I've got this problem where Photoshop gradually 'dies' - the scrubbly zoom begins to go weird and finally stops working. Transform edits just don't respond, the frame comes up but I cannot move the handles. I have the brush toolbar undocked and it flickers. There are some other things. All of this happens after about 20 mins or so, all I can do is restart PS and work for 20 mins, repeat.
I've been using PS for 20 years to do matte painting and digital painting, I'm very familiar with the app but this problem, argh I dunno. My performance settings:
AMD Ryzen 9 5950x
Nvidia 3080ti
64GB RAM
Windows 10
