Comment 0 for bug 1789059

Several times using the master branch with Qt 5.10.1 on Fedora, the GUI has completely frozen. At first I thought it might be related to using my touchscreen because it happened a few times within a minute or two of using my touchscreen with the overview waveforms. That seems to be a coincidence though because I just encountered the bug again without using my touchscreen at all. When this occurs, the audio keeps playing until the end of the track, which allows for a relatively graceful recovery if this happens during a performance (which has happened to me a few times now). I can tell the controller thread still runs okay because LEDs light up when I press buttons. However, there is no change in the audio from manipulating my controller. Unfortunately I have no idea how to reproduce this. The best idea I have currently for attempting to debug this is to run Mixxx in a debugger until the bug happens by chance.
