Make applet hitbox square
I can't click an applet if my mouse is right on the top right edge of the screen. This is bad for UX, and makes it hard to use the desktop.
And maybe related, but the same happens for all button when the panel has the space between the edges.
The applet hitbox is square, and they can be clicked in a corner, unless a panel is floating (and I agree that they should stay clickable on a floating panel). The issue that you're encountering is related to the compositor, where there's a 1 pixel line along the bottom and right screen edges, that prevents interaction (which is a known issue). If you try clicking on the top left corner, the applet there should open.
Now that you mention it, that is indeed true. I hope the floating painel issues get dealt with soon. Thank you for the quick response!
