Bug ID: 444686
Summary: Wayland (?): Agenda view slows down when moving the
mouse
Product: korganizer
Version: GIT (master)
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: agendaview (weekview)
Assignee: kdepim-bugs at kde.org
Reporter: me at dblsaiko.net
Target Milestone: ---
SUMMARY
On my 150% scaled display, moving the mouse over KOrganizer's agenda view makes
it take noticeably long to update, most visible by the red line on the timeline
that shows where the mouse is moving like the mouse was moved but delayed. It
seems to process every mouse move event even if new ones have already come in
which makes it take a long time to become responsive again if you moved the
mouse around a lot.
The issue occurs similarly but way less severely when moving KOrganizer over to
my 100% scaled display. There, just moving the mouse around makes it behave
normally but dragging to select cells still has the same problem. (I'm assuming
it's just not taking as long to redraw the window there so it's less
noticeable.)
I put "Wayland (?)" in the title because I'm not exactly sure if this is
Wayland-specific, I noticed it first when I switched to Wayland though and
haven't tried X11 since.
STEPS TO REPRODUCE
1. (optional) Set display scale to 150%
2. Open agenda view
3. Move/drag mouse around on the table
OBSERVED RESULT
The UI slows down, taking longer to regain responsiveness the more you moved
the mouse around.
EXPECTED RESULT
The UI stays responsive.
