Bug ID: 457359
Summary: Present windows takes too long to display itself and
will close itself immediately when hotcorner is
activated more than once
Product: kwin
Version: 5.25.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-present-windows
Assignee: kwin-bugs-n...@kde.org
Reporter: ashco...@gmail.com
Target Milestone: ---
SUMMARY
When using the present windows effect via the mouse hot corner (Mainly on a
multi-monitor setup), it can take up to 2-3 seconds for it to actually show
itself. This makes the effect appear unresponsive, so naturally you will end up
trying to activate the hot corner more than onces.
Issue with doing that is once you have tapped the corner more than once, and
the present windows effect finally does display itself, it will immediately
close itself due to the double activation of the hot corner
STEPS TO REPRODUCE (Scenario A)
1. Open 10-20 windows on a multi monitor setup
2. Activate the present windows via the hotcorner
3. Observe a long lag time between hot corner activation and the effect
starting
STEPS TO REPRODUCE (Scenario B)
1. Open 10-20 windows on a multi monitor setup
2. Activate the present windows via the hotcorner, then activate the hot corner
again whilst the effect still hasn't shown yet
3. Observe after some time, the present windows effect will show, then
immediately close itself
OBSERVED RESULT
The long lag time with showing present windows combined with multiple hot
corner activation will result in the effect lagging out, then immediately
closing itself
EXPECTED RESULT
Hot corner activation should be disabled once the effect was first called, so
erroneous double tapping of it would not trigger the effect to immediately
close itself before the effect has actually shown.
