When it stops working, is the graphics processor getting unchecked in the preferences? When Photoshop experiences a GPU issue, it will sometimes turn it off in the preferences. then when restarting Photoshop, it can turn it back on too. So when it happens, BEFORE restarting Photoshop, please check the preferences un the the performance section. Is the GPU unchecked at that time when it doesn’t work?
