Description Edward Kigwana 2021-02-25 05:48:34 UTC

SUMMARY
Mousing over applet such that it shows information causes plasma to lock up.

STEPS TO REPRODUCE
1. Mouse over applet


OBSERVED RESULT
Applet appears to be animating the pop up over and over. Apparently ctrl+F keys
don't work so I have to hit the reset button. Happens every time so I removed it from the panel. A bit annoying that an applet can take down the entire shell.

EXPECTED RESULT
Show applet information like in X

Could'nt figure out how to recored screen so I took a screenshot. When opened
spectacle, the busted part froze.

I can reproduce this sometimes on openSUSE Tumbleweed. So far, I've only 
managed to do it by scrolling over the widget, not merely by hovering. Is this consistent with your experience?

Can you please comment what you expect Ctrl+F to do (is this a custom key binding?) and what "reset button" you have to hit (in the settings?)?

I rebuilt the mesa driver with debugging symbols as well. And it was still broken. Apparently glib was busted because when I rebuilt it with debugging symbols the problem went away.

Comment 5 Edward Kigwana 2021-02-25 07:21:23 UTC

@Alois, I was able to replicate the issue as you described as well. I expected ctrl+F1 to take me to the console which doesn't work for me in kwayland but that is a separate issue altogether.
