Redraw Issue, Preview is wrong black or scambled

Question

For years and many OS & PSD upgrades have had this issue where I open a new image and it is scrambled. Usually I can command I to invert, then do again to get back to original values and the redraw works good. Today I get a black file and invert does not fix the issue.  I know that file is good as the layer thumbnail preview is good, and the info palette confirms. 
 
Anyone familiar with this issue. I turned off graphics processor and restarted and seems to be good. Will run with graphics processor off for a few weeks to see if that fixes the issue. Might be time for a new computer this holiday, as am guessing the graphics card might be the issue.

Hi @Mike_Gondek10189183 turning off GPU means that either the Mac GPU is not compatible/underpowered or corrupted somehow. It also means you've disabled most of the newer GPU features like Neural Filters and other advanced options.

Try going to Photoshop Preferences/Technology Preview and check “Disable Native Canvas”.

Unfortunately I have a 2015 MBP that I left on Catalina and PS 2020 just to keep it stable.
