Bug ID: 427506
Summary: Rectangular selection on desktop lags behind cursor
Product: plasmashell
Version: 5.19.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist

Video recording showing the issue
SUMMARY
Mouse selection in the desktop has a considerable latency compared to other
animations in the Plasma environment, such as mouse selection in Dolphin. See
the attached video for a comparison.
This is clearly not a critical bug, but it makes Plasma feel heavyweight. So it
may be worth investigating a bit.
STEPS TO REPRODUCE
1. Create and resize a rectangular selection in the desktop by dragging the
mouse rapidly.
2. Create and resize a rectangular selection in a Dolphin window by dragging
the mouse rapidly.
OBSERVED RESULT
The rectangular selection on the Desktop lags considerably behind the cursor.
EXPECTED RESULT
The delay between selection and cursor should not be easily noticeable, as in
Dolphin.
