Description Alexey Ilyin 2025-02-17 13:09:16 UTC 
Since Plasma 6.3.0 the Glide Effect applies to all window classes, including tooltips (e.g. in Task Manager) and menus, which looks strange and ugly, especially at high rotation angle values ​​in the effect settings.

STEPS TO REPRODUCE
1. Activate the Glide Effect in System Settings' Desktop Effects page
2. Set Rotation Angle value to e.g. 15
3. Log out and log in (or restart Plasma)
4. Open context menu on the Desktop or in any QtWidgets-based App like Dolphin

OBSERVED RESULT
The menu will open with a Glide Effect

EXPECTED RESULT
The menu will open without a Glide Effect

SOFTWARE/OS VERSIONS
OS: openSUSE Tumbleweed
KDE Plasma Version: 6.3.0
KDE Frameworks Version: 6.10
Qt Version: 6.8.2
Session: Wayland
Comment 1 Alexey Ilyin 2025-02-17 13:13:58 UTC 
Interestingly, toggling the effect on and off within a single session reverts to the Plasma 6.2.5 behavior, meaning the effect only applies to regular windows with decorations.
Comment 2 Vlad Zahorodnii 2025-02-17 14:56:25 UTC 
It should be fixed in 6.3.1
