Comment 10 for bug 90631

I've been experiencing this issue as well. It occurs on my multi-user system.

I am able to reproduce this:
1. Log in as user A
2. Via the user applet log in concurrently as user B
3. Log out as user B
4. Enter password of user A
5. Scroll mouse wheel and see the CPU utilisation rise.

A quick workaround is Alt+F2 and running "imwheel -k". I admit - a launcher for a script would be even quicker.

I don't have time for debugging this but i don't see it as relevant as the development of imwheel has stopped 5 years ago. But at least I've found this bug report with a nice new alternative - btnx. Thanks!
