effect not working on an hdr monitor #105

Hi! I'm experiencing issues with my external screen related to HDR: whenever HDR is enabled, windows become opaque (first screenshot). Reverting to a normal (SDR) profile in KDE settings "fixes" the issue (second screenshot) but is not quite ideal...

Issue seems present on latest develop and main branches, I'm currently on the AUR's kwin-effects-forceblur 1.3.1-1

I'll do my best to stay in touch in case you want to test a fix and don't have a HDR monitor at hands

I don't have an HDR monitor, but I did also run into this issue after enabling a color profile. It occurs when either fake blur (both main and develop) or antialiased rounded corners (only main) are enabled. Are you using either of those?

I improved the rounded corners implementation on develop because the previous one was horrible, so the issue shouldn't occur anymore. You need to restart KWin after installing a different version of the effect, otherwise it'll keep using the old one even if you toggle it in settings.

I'm indeed using fake blur with a manually-blurred image.

I compiled and installed from the develop branch (commit acde198dad) but enabling fake blur still triggers the bug. Nice new features tho

Noise also stops working, even in the stock blur effect.

Fake blur should work now on develop. For now you'll need to toggle the effect after changing display settings.
