It would be good to get a backtrace if someone can reproduce.

2640? The issue is gone for me, but may be affecting other systems.

Another crash related to the screen I got: #2144.

I think more info is needed... I reproduce the same steps several times daily and qTox doesn't crash.

[17:42:21] Welp: https://bugreports.qt.io/browse/QTBUG-42985 https://bugs.launchpad.net/ubuntu/+source/qtdeclarative-opensource-src/+bug/1450137 https://bugs.kde.org/show_bug.cgi?id=340267
[17:42:27] It's a known upstream bug apparently

Since the upstream bug was closed long ago, I'll also close this one.
