OBS application crashes on trackpad tap events

Question

OBS crashes (segfault) when I tap the trackpad while the mouse is over the OBS window. Using the mouse does not cause this crash.

The guy on this forum post ran into issues with OBS, specifically mouse and crashing issues.

My installation ran into the same problem running on an XPS 13, x64 Ubuntu 14.04.5 LTS.

[1]    17198 segmentation fault (core dumped)  obs

Here is the output of gdb ods... seems to be a qt5 problem.

Program received signal SIGSEGV, Segmentation fault.
0x00007fffda837cbb in ?? () from /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so

That was same version used to build the obs, here is the related build log. You better go with bug report against obs.

But before reporting, test the last unstable build from OBS Studio Unstable PPA

sudo apt-add-repository ppa:obsproject/obs-studio-unstable
sudo apt-get update
sudo apt-get install obs-studio

The Linux version of OBS is still under development and contains many bugs, but if you're feeling brave, and can install Ubuntu PPAs, then you can give this a try.
