No desktop effects

I’m running SESE Leap 42.1 on a machine with AMD videocard HD 7700 and I don’t know how to enable 3D-effects. I have fglrx driver installed, and Radeon Control Center tells me that OpenGL vendor is AMD. On previous versions of SUSE I used to go to the Desctop Effects in System Settings to check out OpenGL parameters, but in 42.1 I don’t have an OpenGL tab in Desktop Effects. What should I do to enable OpenGL and 3D effects?

Be sure you are running systemsettings5 if you upgraded then the KDE4 version may still be in the menu

I do use systemsettings5.

Don’t know if it is related, but when start systemsettings5 from the console and navigate to Desctop Effects I see this message in console:

Constructing a KPluginInfo object from old style JSON. Please use kcoreaddons_desktop_to_json() for “/usr/lib64/qt5/plugins/kwin/effects/configs/kcm_kwin4_genericscripted.so” instead of kservice_desktop_to_json() in your CMake code.

And when I try to preview(???) the effect (pressing the button with the film icon) the app crashes with the segfault.

Are you sure you have all the correct repositories? Did you install any of the newer KDE stuff???

Sounds like maybe you have incompatible repos.

Actually I don’t remember if I updated SUSE or just installed new version on this particular machine. But I do remember that visual effects worked some time ago because I like to have background of my konsole transparent and I notices that something is wrong about effects because it became non-transparent.

fiy if kwin5 crashes desktop effects are turned off automatically so check if composing is on and see check the state of desktop effects
you can filter the desired option in ksystemsettings5
if you can’t find the desired option write opengl in the top right corner the desired button should stand out

Thanks for the hint with the search bar! OpenGL settings were moved from Desktop Effects to Display and Monitor -> Compositor (but WHY!? that’s irrational). The issue is solved.
