When the translucency desktop effect is enabled, minimizing firefox causes it

Jul 03 15:18:42 Pallas plasmashell[10446]: QUnifiedTimer::stopAnimationDriver:
driver is not running
Jul 03 15:18:42 Pallas plasmashell[10446]: kpipewire_logging: invalid image
"EGL_BAD_PARAMETER"
```
Each of the 'TypeError' messages is generated when minimizing a firefox window.
After the last messages appear together (stopAnimationDriver/
BAD_EGL_PARAMETER), video playback continues for a short time (maybe 1 minute?)
but eventually stops. Restoring one of the browser windows from minimized
during this time, the page initially appears OK, but any interaction has no
result... Until all of the firefox windows are restored, and then all of the
input that was sent to each of the windows simultaneously happens, and video
playback continues (usually at extremely low quality until the page is
reloaded)
EXPECTED RESULT
No freeze with translucency effect enabled

ADDITIONAL INFORMATION
Sorry if this is filed in the wrong place, It's not entirely clear to me where
bugs in desktop effects should be reported. Any advice appreciated.
