I could reproduce it two other times. The last one was not with a middle click, but when clicking on a form button.

When switching the desktop and coming back, the incorrect rendering is still present, but scrolling makes it disappear.

Editing text in StackExchange yields similar problems (always reproducible). I'm not sure whether this is related.
