I am wanting to use an alternative to Kvantum. And they best theme I found that seems to suit blur transparent windows is this theme: Alpha - KDE Store
But this theme doesn’t seem to blur at all. And is glitching. I notice this with any color theme that has any kind of blurred transparency. And it is see though.
The default Blur effect only blurs windows that “ask” for it e.g. Konsole. If you want to force blur on other windows you can use kwin-effects-forceblur
I can’t get the same effect as you. I have a blur effect. But it’s nowhere near translucent as you have yours. Mine is like very dark when it comes to Dolphin. But Discover looks great.
Okay. Yeah. That is exactly what happens to me. I think I’ll wait until the bug with KWin is fixed. Because all I see is mostly a dark blur with no translucency. Even with thickness set to 0.
I think I found the reason for the glitching. When using a non-opaque color scheme, KWin doesn’t know that the window is translucent, so it doesn’t paint anything behind it.
I added an option to mark all force-blurred windows as transparent (“Paint windows as non-opaque”) to kwin-effects-forceblur on the develop branch. The fix will unfortunately result in high GPU usage and stuttering if you have a decent amount of unminimized windows open.
