Bug ID: 443971
Summary: Present windows effect in desktop grid is missing its
animations
Product: kwin
Version: 5.23.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-desktop-grid
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
I've noticed this after the recent 5.23 upgrade on the Wayland session.
When both the desktop grid and the present windows effects are enabled, the
desktop grid effect is using the present windows effects for showing the
individual windows in its various tiles.
The present windows effect itself is showing an animation of the window
positions, so that windows don't suddenly jump to their position in the
presentation layout. This is working as intended.
However, in the desktop grid after the 5.23 upgrade on wayland, this window
animation is missing for both the transition-in and transition-out phases of
the desktop grid, which means the windows suddenly jump to their presentation
positions. This is especially noticable for maximized windows when selecting a
desktop from the grid where it zooms back in.
STEPS TO REPRODUCE
1. enable desktop grid and present windows effects
2. use a 3x3 grid layout and any present windows layout (eg. natural layout)
3. have multiple windows open, one of them maximized
4. toggle the grid
5. toggle grid again
OBSERVED RESULT
The individual windows suddenly jump to their positions in the tile's window
presentation layout. When selecting the desktop again from the grid (aka.
zooming back in), the window jumping is very noticable and distracting,
especially for maximized windows.
EXPECTED RESULT
The desktop grid animation and present windows animations should both work at
the same time, so that windows smoothly move to their intended positions, just
like when toggling the present windows effect alone.
SOFTWARE/OS VERSIONS
Linux: Arch
KDE Plasma Version: 5.23.0
KDE Frameworks Version: 5.87.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
This was not the case prior to 5.23 on the X11 session, and everything was
working as expected.
