In many cases my mouse is stuck on the busy cursor. I'll use applications like gajim or nicotine and have to wave it around and play with menus and everything to get it un-busy. This is rather frustrating, since the resize-pane cursor doesn't come up when I'm resizing a pane, so it's rather a pain to know when to click and drag.

If I start gajim, I can have it running for hours and when I switch back to the gajim window I'll still get the busy cursor a fairly often, though. Is the timeout configurable?
