Bug 494492

Description:
Since updating to Plasma 6.1, I have noticed lower framerate performance when playing Minecraft in fullscreen mode. Upon exiting fullscreen, the framerate increases significantly. Despite waiting for the Plasma 6.2 update, the issue persists, so I am filing this bug report.

Fullscreen: https://ibb.co/BTHw9xy
Windowed: https://ibb.co/27jR4hz

Steps to Reproduce:
1. Launch Minecraft in fullscreen mode.
2. Observe the average framerate while playing in fullscreen.
3. Exit fullscreen mode.
4. Compare the average framerate between fullscreen and windowed modes.

Observed Result:
The framerate in fullscreen mode is lower than expected. When exiting fullscreen, the framerate increases significantly, even though fullscreen should theoretically provide better performance due to direct scanout.

Expected Result:
Framerate should be higher or at least comparable when playing in fullscreen mode, as it should benefit from direct scanout and improved GPU resource allocation.
