Somehow, the reminder popup in Evolution got resized to full screen, so every time it pops up, it covers the entire screen. How can I resize it back to its original size?
I’ve tried all the usual system tricks, but none of them work: I can’t grab the edge of the popup, so nothing that requires me to do that works. I can’t drag the popup at all. Alt-F8, Super-Down, and F11 have no effect. Alt-Space shows the system menu, but resize is grayed out.
Details: Evolution 3.36.5-0ubuntu1 on Ubuntu 20.04.3, with dual monitors. (The popup appears on the second monitor.)
