segfault backtrace with kwin

When starting "DRI_PRIME=1 minetest", single player mode, right when the
loading screen seems to be finished, x.org crashes, when
* Using dri3 prime offloading AND
* compositing is active (tested with kwin_x11 opengl compositor and compton
--backend glx)

It does NOT crash
* with dri3 offloading when no compositor is running
* with dri2 offloading (DRI_PRIME=1 LIBGL_DRI3_DISABLE=1 minetest)
* starting a compositor after starting the game

I'm getting different backtraces, I'll attach the three I have got so far.</pre>
