Restarting Kwin makes the shadow windows disappear.

Does the issue happen in 6.5 or 6.6? If it does, please attach the output of `qdbus org.kde.KWin /KWin supportInformation` to this bug report.

Hi this is me but under a different name since I don't go by that name anymore, but the bug doesn't happen anymore, I'm really sorry I forgot I ever reported this
