Cannot reproduce this here. How long does it take to crash for you?
(In reply to Tobias C. Berner from comment #2) > Cannot reproduce this here. … OK! Crashes seemed to occur when starting a new session, or restoring a session. I found a number of crashing bugs in the KDE area, most noticeably: 408701 – Crash at restore page > Start New Session https://bugs.kde.org/show_bug.cgi?id=408701 I took a hint from a more recent bug: 415680 – QtWebEngine crashes with QtCurve on exit https://bugs.kde.org/show_bug.cgi?id=415680 In system settings, I changed: * application style from Breeze to Oxygen * window decorations from Breezemite dark to Oxygen – after which, Falkon ceased crashing. Touch wood. Reverting application style and window decorations did not make the bug reproducible. I'll add a screen recording to KDE bug 408701, with reference to some of the other crashing bugs. Closing (unable to reproduce) but feel free to reopen if necessary.
