QGC crash restoring from task bar

HI there

I am running QGroundControl v3.2.4-BlueRobotics-Rev3 on a Debian Stretch PC with LXDE.

It minimizes to the task bar fine, but every time I restore it, it crashes.

Just wondering whether anyone else has seen this, whether it is specific to the BlueRobotics version, and whether there is anything logged which would help troubleshoot.


I just noticed that I don’t get the same crash on another Debian/LXDE machine running BlueRobotics-Rev2 of QGC 3.4.2, so I will start troubleshooting from there.

Hi @Mark_USR,

Can you send a log ?
Run export QT_LOGGING_RULES="*.debug=true" , and start QGC via terminal, after the crash send the log with pastebin.

I will get the log info ASAP.

In the meantime I have tried with rev2 and I get the same crash.

After some troubleshooting I have determined that it only happens when there is an incoming UDP video stream:
Video as main display → crash
Video as HUD (lower left inset) → crash
Video as HUD but HUD hidden → crash
Incoming video port changed to non-existent incoming stream → no crash
so I am guessing something to do with my gstreamer installation.

Thanks for your attention.

OK, log output went way past the buffer on my terminal window… I will redirect to a text file and upload it.
