White screen. Can't change background color, or draw ANYTHING.

in Other
Anyone experiencing this problem? I've been away from the application for almost 18 months. Upgraded Ubuntu from V20 to V22.04.5 LTS I started BricsCAD tonight, and encountered an error:
(1) Redsdk API error code
After some search, I learned that this has something to do with a hardware rendering issue. So I went into the settings menu and switched to software rendering. I restarted the app, and no more Redsdk error message. But my model space and paper space backgrounds are white, and I can't draw ANYTHING. I can select different colors for the backgrounds in the settings menu, but the screen remains white.
