dock doesn't respond to clicks on minimized java programs and the corner mouse bind stop working

[Franco]

Suddenly, my minimized java programs in the dock stop responding to clicks, so i cant maximize/switch to them. And at the same moment, the top-right corner bind that I have to "scale", stop working (but super+w works)

Thank you for your bug report. That bug is quite old, is there any chance you could test if that's still an issue with recent version? Could you reproduce the problem every time, and in which case what steps did you use?
