Unfortunately it's been year and a half since the report, and in that time I've replaced that OS with a clean install of newer version, which included setting up graphics and drivers from scratch and in a different way. I have no idea how to get back to the old setup and reproduce the issue, but it is absent in the new setup (with KDE 5.18.5), so something helped. I half-hoped that even without my setup available the backtrace and description by themselves would be enough to shed some light, but apparently that's not the case, so the issue can be closed I guess...
