Gets fixed with the relaunch.

I am experiencing this as well. Here is a video.
No. It did not happen before.
I have restared the software and tried it on a new file, and it now seems to work.
I have opened the file in which the problem occured and it now seems to work there as well.
You might consider the bug closed (for now)...
Did it ever happen for you with previous versions?
Does it get fixed if you unplug the second monitor?
Do you notice anything similar with other panels and dialogs?
