Git commit 65bbd83a9340005250c101baea593198d2c41283 by Waqar Ahmed. Committed on 11/10/2024 at 15:21. Pushed by waqar into branch 'master'. Fix bad qobject_cast qobject_cast after destroyed signal is just wrong. It will cast to null and we will end up removing nothing M +1 -1 apps/lib/texthint/KateTextHintManager.cpp https://invent.kde.org/utilities/kate/-/commit/65bbd83a9340005250c101baea593198d2c41283 can you try again after recompiling with the linked commit? Amazing! I can confirm that fixes it; thank you so much! MVP of the day! 👏👏👏 |
Everything KDE from today's git master STEPS TO REPRODUCE 1. Have two sessions 2. Launch Kate 3. Switch sessions (I do it from a button I put on the toolbar) [This often causes the window to resize because window sizes are saved on a per-session basis] 4. If the window got resized to be maximized, immediately quick-tile the window to the left or right side of the screen with Meta+Left Arrow or Meta+Right Arrow OBSERVED RESULT Kate crashes with the following backtrace 100% of the time: Core was generated by `/home/nate/kde/usr/bin/kate -b'.
