Did you try switching the OpenGL version used by the compositor?
Maybe turning it off completely helps.
Sorry but i don't think i understand your advice.
"Did you try switching the OpenGL version used by the compositor?" --> Do you mean in System Settings - Workspace Behaviour - Compositor? If yes, my choices there [for "Rendering backend"] are simply OpenGL 2.0 [= my current setting], OpenGL 3.1 [which i used initially after originally installing Maui, until i changed it to 2.0 as we all discussed here https://forums.mauilinux.org/showthread....9#pid39439 ], or XRender [which basically means important Desktop Effects stop working, meaning there's not much point me persisting with KDE].
"Maybe turning it off completely helps" --> how do i do this? Do you mean selecting XRender? Maybe i'm looking at the wrong place in Settings? Either way, gaining system stability [if that worked] at the expense of losing my Desktop Effects is a price i can't pay. Without DE, KDE loses a large amount of relevance to me, inferring i could just replace Maui with Mint 18 Xfce+Compiz .
((EDIT)) My apologies, i just tried XRender now, & all my DE seem to still work, except for Desktop Cube. That's a pity, but not mission-critical compared to ongoing functionality of Present Windows, Desktop Grid, Show Desktop etc. I'll try it this way for a while & see if the crashes go away. I have to say though... this is the identical h/w which til recently ran Mint 17.3 KDE4, & used OpenGL 3.1 compositing, & did NOT have all these crashes.
((EDIT2)) Oh dear, without OpenGL, i also lose Wobbly Windows as well as the Cube. It gets sadder & sadder...
