Describe the bug
Kitty 0.34.0 running with a wayland backend on KDE Plasma 6.0.3, on an old 2015 Macbook Air with an Intel HD6000 graphics chip and the latest i915 driver.
background_opacity 0.8
dynamic_background_opacity yes
With background_blur=0 kitty + desktop looks like this:

With background_blur=1 or any other integer > 0, kitty looks like this:

If it isn't clear - the background is now almost entirely black & opaque. That darker rectangle is a window behind kitty - so there is some transparency - but as you can see it's blurred beyond all usability. I tried various values between 1 and 64 and there's no discernible difference - just total blur!
Also, when background_blur > 0, resizing the window causes this:

To Reproduce
Steps to reproduce the behavior:
- Install KDE 6.0.3
- Install Kitty 0.34.0
- Set kitty.conf values as above.
