Flashing screen when opening folder for new project

I discovered an interesting bug. When there are too many subfolders is a folder, Adobe Rush starts erasing and redrawing the window a rate of about once per second. If the folder you want is not one of the ones that fits on the screen, you can't navigate to it. You're completely blocked.

Basically, I think that Adobe should not try to reinvent the file manager and just use the one that's built into the OS. Almost every problem that I've had with AdobeRush has been because of the inadequately reinvented file management and folder navigation.
