The backtrace is rather incomplete and the software stack is outdated. I would recommend to at least update the drivers.
i was change GLMode to TFP in kwinrc
(In reply to comment #2) > i was change GLMode to TFP in kwinrc and now works great :)
Using anything but TFP does not make sense unless you want to break your system. Because of that it has been dropped in master which renders the bug invalid
