Bug ID: 499930
Summary: Clipboard Popup opening is delayed on a scaled
display, and when opening on a display with a
different scale factor than the one it was previously
opened on
Classification: Plasma
Product: plasmashell
Version: 6.3.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Clipboard widget & pop-up
Assignee: plasma-b...@kde.org
Reporter: eamonn...@protonmail.com
Target Milestone: 1.0
SUMMARY
Note: This issue only affects multi-display setups. Single scaled display
setups (i.e. a laptop with a scaled display) do not seem to exhibit this issue.
The clipboard popup has a 1-2 second delay if you try to open it on a scaled
display. It has the same delay if you open it on a scaled display and then try
to open it on a non-scaled display for the first time.
When opening multiple times across multiple displays with the same scale factor
(i.e. 100%) it opens instantly.
When opening on a scaled display (i.e. 150%) it will have a delay. It has this
delay each time you try to open it on a scaled display. However, when moving
back to a non-scaled display (i.e. 100%), it will have a delay only the first
time.
STEPS TO REPRODUCE
This setup assumes at least one scaled display, and at least two non-scaled
displays.
1. Open the Clipboard Popup on a scaled display.
2. Observe 1-2 second delay on each attempt.
3. Next, move cursor to non-scaled display and open the popup.
4. Observe the same 1-2 second delay, but only on the first attempt. Subsequent
attempts will be instant.
5. Finally, open the popup on unscaled display #1. It should be instant, or the
first attempt may have a delay if the previous display was a scaled display.
Then, move to unscaled display #2. There will be no delay.
- In other words, moving between unscaled displays, there is no delay.
There is only delay the *first time* when going from a scaled display to an
unscaled display. However, scaled displays will have delay every time.
OBSERVED RESULT
There is a delay behaviour when opening the clipboard popup across
multi-display setups with a variety of scale factors.
EXPECTED RESULT
There should be no delay when opening the popup on any display scale factor.
