Application: falkon (24.12.3) ApplicationNotResponding [ANR]: false Qt Version: 6.9.0 Frameworks Version: 6.12.0 Operating System: Linux 6.14.1-1-default x86_64 Windowing System: Wayland Distribution: "openSUSE Tumbleweed" DrKonqi: 6.3.4 [CoredumpBackend] -- Information about the crash: Falkon started crashing on start-up. This started after I tried to share a page link via KDE Connect. I have right-clicked on a webpage, and selected to share to some other device via KDE Connect. Instead of the dialog being open to select the target device Falkon crashed. Now after this each time I try to start Falkon it just crashes. The reporter is unsure if this crash is reproducible. -- Backtrace (Reduced): #5 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at pthread_kill.c:44 #6 0x00007f886fa9b453 in __pthread_kill_internal (threadid=<optimized out>, signo=6) at pthread_kill.c:89 #7 0x00007f886fa41cb6 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #8 0x00007f886fa2938b in __GI_abort () at abort.c:73 #9 0x000055c7402fc9e7 in msgHandler (type=<optimized out>, context=<optimized out>, msg=<optimized out>) at /usr/src/debug/falkon-24.12.3/src/main/main.cpp:41 Reported using DrKonqi

Hello and thank you for the report. I do not see anything directly related to Falkon in the backtrace. Because backtrace in Thread1 mentions stuff around GPU stuff I would try to disable the GPU acceleration in Falkon settings (if it was enabled before). The falkon profile is located at around "home/<user>/.config/falkon/profiles/<profile, often default>". Open settings.ini and modify it > [Web-Browser-Settings] > hardwareAccel=false *NOTE*: It should only be one in the file, otherwise it may not work.
Yeah disabling hardware accelleration made it launch again. Although I do not see any update of Mesa in between, still the same version as before. The only bigger change I can see so far is that Qt has been updated from 6.8.2 to 6.9.0.
The Qt6.9 only supports the "angle" backend and the falkon hardware acceleration tries to enable "desktop" backend. This could be causing problems on older versions. the soon to be released version fixes this. I do not know if this is the real problem or not at the moment.
Yeah looks like you are right. This is the command line output if I start Falkon with HW accel enabled: Only --use-gl=angle is supported on this platform.
