Bug ID: 418302
Summary: Weird behavior in Firefox if window was maximized last
time it was used
Product: kwin
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: anon...@openmailbox.org
Target Milestone: ---
SUMMARY
I noticed this weird behavior in Firefox lately. I hope I can explain it
properly because English is not my main language. Anyway look at the steps to
reproduce it.
STEPS TO REPRODUCE
1. Open Firefox and maximize it
2. Close it
3. Open it again
4. Right click on any part of any page
5. Right click menu appears directly under the pointer so if you click and
release normally the first element in the menu will be selected
6. Click on the maximize button again, you'll notice the window appears to
maximize again but in some weird glitchy way
7. Right click again, the menu appears normally
8. Close and repeat, it happens every single time
OBSERVED RESULT
It appears that when restarting Firefox if the last time it was closed while
maximized, right click menus appear shifted and under the mouse pointer,
causing frustration while typing. It is only fixable by maximizing the window
again. It appears that the window manager does not recall Firefox's last state
properly.

Not sure if it's a bug with Firefox or the window manager. It doesn't seem to
be caused by my settings because it happens on a clean firefox profile too.
