Screen Constantly Going Blank

Windows. I open the app, it's blank. Happening all the time. Randomly comes back for a bit. Goes away again. If I kill it in task manager, it will open and be there, until it goes blank again.

No source file, test, or entry point is named. Start by reproducing the blank-screen behavior on Windows after launching the app and gather the relevant client information; done means identifying the cause, fixing the recurring blank state, and verifying that the app remains usable after relaunches.
