Rendering bugs - Layer panel previews not rendering and selection not appearing after mouse release.

Hello,

I tried to use Photoshop elements yesterday and I noted that the behavior of the application  has changed.

01.

At various times the thumbnails in the layers panel do not render - they just appear as they default grey and white checkers even though the layer has objects that should be in the preview. Cutting some of the layers sometimes forces a render of the preview.

02.

I every time I attempt to make a selection with any tool the marching ants around the selection disappear. I can see my selection as I'm making it, but when I release the mouse, no selection is visible in the image (even though it *did* creation the selection). The selection appears if I flip back and forth to another image window. When I finally do see the selection, the ants are not moving, the ants are dead.

I'm really hoping that there is an easy fix for this because it's very hard to work when I cannot see my selections and my layer previews.

I have tried the 'reset my preferences' solution, but the bugs still persist. I've also turned off the setting that uses my graphics card in the settings.

I have a nvidia gtx 3070 graphics card if that might be relevant information.

Notice two things about my attached image:

A. My selection only shows 'outside' of my image (the ants are *not* moving).

B. The layer preview pane is *not* reflecting what I painted.

Thanks.
