[Solved] No blur in Wayland with KDE

So this seems trivial, but actually using Wayland is rather difficult because of this issue - with current Plasma themes, you can't read interface elements or pretty much anything, as all of them have a (semi) transparent background, including Plasma panels and widgets and stuff. So it gets pretty annoying.

Previously I had an "old" i7 2nd gen workstation with integrated Intel graphics, and it ran without issues whatsoever - blur worked; Wayland was my daily driver there. But on April was able to upgrade to a i5 8th gen workstation, also with Intel integrated graphics (lspci says it's an Intel Corporation UHD Graphics 630 (Desktop), I set it up as "intel i965" in make.conf). Reinstalled Gentoo on it but... blur does not work in Wayland - only on the lock screen.

In X, it works with no adjustments whatsoever. This only happens in Wayland and I can't even figure out how to troubleshoot this nor have got any help about it.

Tried creating a throwaway user to test this - blur also wasn't working on there. Got a Fedora (34?) KDE live usb, one of those who uses Wayland right out-of-the-box, and things are blurred there. So all of that leds me to think there's something like screwed configuration on my part, but I don't know where else to look.

The Wayland SSDM logs don't seem to say anything helpful, but will post them if needed. Nor the output of 'qdbus org.kde.KWin /KWin supportInformation'.

Any help on this would be awesome.

[Edit]

Turns out I'm a huge idiot.

After reading from head to toe every wiki page about Intel (Gentoo, Arch...), checking (and trying with) every USE flag and CARDS vars, checking every parameter in my Kernel config, even installing the gentoo-kernel-bin, brute-force copying a kernel from Fedora, ranting about it everywhere...

I just had to install plasma-meta.

I don't even know why I didn't had it installed in the first place, maybe I imagined it pulled all @kdegraphics, @kdeedu, @kdegames and all stuff like it did before and just pulled plasma-desktop. But as that warning message says, plasma-desktop will leave users "figure out missing features on their own". Fuck me sideways.

Now I have to figure out why when the screen turns off automatically (powerdevil) it won't turn on again when moving the mouse, pressing something on the keyboard or doing

Hmm. You seem to have a 'Coffee Lake' CPU. Right? According to this page, VIDEO_CARDS="intel i965 iris" should be used.

Please post the output of

Code:

lspci -nn | grep -i VGA
Code:

emerge --info
Code:

dmesg

You may want to use wgetpaste for the output of 'dmesg'.

googling "plasma transparency 5.23.3" returns some results, have you investigated them. (I'm not a kde user)

I don't know if it's related, but there's an error message in 'dmesg':
