Description AK-47 2020-05-17 01:25:41 UTC

SUMMARY
When moving, minimising and restoring Firefox running with Wayland enabled, the effects only apply to the frame. The content doesn't have the affect applied to it.

STEPS TO REPRODUCE
1. Enable Magic Lamp effect and/or Wobbly Windows
2. Run Firefox with either one of the following:
 (a) MOZ_ENABLE_WAYLAND=1 firefox
 (b) firefox-wayland
 (c) The "Firefox on Wayland" menu item.
3. Move, minimize or restore the window. 

OBSERVED RESULT
The content of the window remains unanimated and does not have the effect applied to it, making it seem "detached" from the frame. The wobble or lamp effect applies to just the frame.

EXPECTED RESULT
The whole window should have the effect applied to it, not just the frame.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.70.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION
This is a long-standing issue. It only affects the Wayland version of Firefox, not Firefox under XWayland.

This should be fixed with Plasma 5.19.
