Here it is, I hope it is more verbose now. This kwin version if from git but switched to Plasma/5.9 branch. Hope this helps.
This is the first time I see a backtrace with good debug symbols from an Arch user! Good job! It looks like this is the well known issue of Nvidia discarding the mapped memory on vt switches. *** This bug has been marked as a duplicate of bug 344326 ***
