[solved] Kwin composting effects after d-u

[jaegermeister]

Hello,

it's already a couple of weeks that I have this problem, but I wanted to see if, in the meantime, some update could solve it, which didn't happen.

Basically, after installing Desperado 12.1 all composting effects in kwin did run smooth. After d-u (a couple of weeks ago), just *SOME* (!) of them like for instance wobbling windows, cube desktop, genius lamp, circular window changer do not work anymore (kwin says it cannot activate those) while all the others (e.g. translucency, presentation, etc.) are working correctly.

This is the xw8400 HP workstation I have quoted in the other email about successful install and currently runs an NVIDIA PCIe card. Here is inxi -F:

I tried the following:

-updating the NVIDIA driver
-renaming .kde/ and creating a new one
-changing video card (right now there's a Quadro FX3500, also tried a Geforce 9400GT and 8500GT)
-waiting a d-u which implied some kde/xorg update

Nothing has worked. This thing is puzzling me.
Should I reinstall with 12.1.1 (maybe it's a known bug) or what?

Thanks

Grässlin - kde developer of kwin - sometimes deactivates effects, eg: window shadow is only done by window decoration theme - oxygen.

Hi,

Under Systemsettings -> Desktop Effects -> Advanced are some options for OpenGL Rendering etc. Did you play with that? In my case (it is an AMD Radeon) I had to deactivate the OpenGL2 Shaders for some effects to work.

When I did a D-U recently OpenGL was  switched to XRender without me knowing about it. It took me a while to figure out what had happened.

I also didn't figure that out! (we are too used to speed to sometimes notice details...)
That did the trick!
Thanks!
