[SOLVED] KDE/plasma 5.23.3/5.88.0: desktop effects "unsupported"

I've only just noticed this and I can't trace it to a specific upgrade, but with frameworks 5.88.0 and plasma 5.23.3, a bunch of effects such as wobbly windows are not working any more (and in settings->Workspace Behaviour->Desktop Effects they are only shown if "Exclude unspported effects" is unchecked).

This is on integrated intel graphics.  It makes no difference whether I select OpenGL 3.1 or 2.0 in the compositor settings.  As far as I can tell, there are no issues with OpenGL.  I'm not sure what else I should be looking for?

There are issues with OpenGL. llvmpipe is the software renderer. Post a xorg.0.log and

sudo dmesg
printenv

which integrated graphics exactly?

Re: [SOLVED] KDE/plasma 5.23.3/5.88.0: desktop effects "unsupported"

Update: This is kernel-related.  No hardware acceleration under 5.15.2(-zen); everything works fine with the arch LTS kernel (5.10.79).

Edited to add 5.14.16-zen works fine too, so workaround is to downgrade the kernel

• Xorg.0.log

• dmesg

Graphics are Intel Corporation Iris Plus Graphics G7 (rev 07) (on a Dell XPS 9300)

Thanks @V1Del

You could drop the guc parameter. and maybe follow: https://gitlab.freedesktop.org/drm/intel/-/issues/4067

Thanks.  Dropping guc works.  I'll keep an eye on the issue.

Hi, do you have a bug report for the kernel issue? Is it being tracked somewhere?
