DESCRIPTION
Attempting to apply any window open/close effects which utilize shaders on KWin 6.7.0 freezes the desktop for 10 seconds and the effect is not applied. This was not the case on 6.6.

STEPS TO REPRODUCE
1. Install a window open/close effect (Example: Incinerate from schneegan's Burn My Windows)
2. In Animations settings page, choose it and press Apply
3. Notice time taken to apply effect
4. Attempt to open or close any window

OBSERVED RESULT
Effect takes a long time to load while freezing the rest of the desktop, while still not working afterwards.

EXPECTED RESULT
Effect loads quickly and works correctly as it did in Plasma 6.6.5.
