Hmm, I thought this crash had been fixed long time ago... If you're able to reproduce the crash, could you please install kwin debug packages and attach a new backtrace to this bug report? (the current one lacks debug symbols) (In reply to Vlad Zahorodnii from comment #1) > Hmm, I thought this crash had been fixed long time ago... If you're able to > reproduce the crash, could you please install kwin debug packages and attach > a new backtrace to this bug report? (the current one lacks debug symbols) I cannot reproduce on this machine right now. Maybe Red Hat already deployed a fix to Fedora. I will reopen, if I manage to reproduce this issue.

[nightcolor] Fix division by zero Summary: If qAbs(targetTemp - m_currentTemp) is less than TEMPERATURE_STEP, then it will result in a division by zero.
