Description Andrey-Mattias 2024-10-28 18:55:50 UTC

SUMMARY
Grid view of virtual desktops is broken if you set animations speed to a maximum position
(i set animations speed to a maximum position to remove animations in Plasma)

STEPS TO REPRODUCE
1. Set animations speed in "quick settings" in "system settings" to a maximum position
2. use shortcut to open Grid view of virtual desktops
3. observe

OBSERVED RESULT
Application windows on every virtual desktop in Grid view of virtual desktops are ultrasmall and downscaled (roughly to ~18% of their intended area) so they fill only <25% of corresponding virtual desktop.

EXPECTED RESULT
Application windows on every virtual desktop in Grid view of virtual desktops are scaled to be as big as possible and to fill most of corresponding virtual desktop area (~80%)

ADDITIONAL INFORMATION
If you set animations speed in "quick settings" in "system settings" to any position but a maximum one, bug goes away.
---
I can't make a screenshot of a Grid view of virtual desktops with Spectacle for some reason. Should also be a bug, xD

Update ExpoCell contentItem position upon its parent change

Since the position of the contentItem depends on the position and scale
of the parent item, make sure to re-evaluate it when the parent changes.
