Selecting FILE NEW Dialog in Photoshop 2020 Brings up a “Flashing” Page Window with the Square Previews of Documents Types & Sizes. So I Had to Change to "Use Legacy New Document Interface" Setting in General Preferences Pane.
(Strange... Turning off WiFi Stops this from Happening) but Legacy setting is fine for now anyways. ~ RpH
Sorry to hear that the New Document Dialog flashes in Photoshop, could you please try deselecting "Use Graphics Processor" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?
I Unchecked “Use Graphics Processor” and Unchecked "Use Legacy New Document Interface." Still Flashing at New Doument Window. That was a Very Good idea to try that though. It does Stop Flashing when I Turn Wifi Off Temporarily. Thank you for the idea!.. I'll use the "Legacy" work-around for now. I Actually Like The Legacy Setting Better than hunting through all those Boxeswith the Tiny Type for the right New document. It's quicker and easier to see.
And the problem remained!!!!!! The window flashes! In cc2019 everything works!!! And at the start screen, when you click on the "create new" button, the old interface starts at all!!! Really it is impossible to correct it and to start such crude product, already there were so many updates!!! Terrible!!!!!!!
