Hard system crash when changing waveform display type during playback

[Kev]

I just installed Mixxx version 1.11.0 (build r3862) on my machine, a Lenovo e420 running CrunchBang Waldorf Stable. Mapped an external MIDI controller and had a track playing on Deck 1. During playback I was examining interface and other options in Options / Preferences / Interface.

"Display type" was set as "Filtered (GL)," the default setting. I clicked one of the Qt settings while the track was playing and my system froze immediately and was unresponsive (no mouse movement either). Track began stuttering at current playback position. I had to do a hard reboot to recover.

I tried to replicate the behavior after rebooting, but Mixxx didn't crash again. The display type updated as I chose it during playback. So, I don't know whether this was a one-off or might indicate some low-level bug that will occur occasionally. So far as I know, I wasn't running any other background processes the first time that wouldn't have been running the second time. Maybe some background OS process was involved the first time?

Anyways, realize it's a low-priority issue, but thought I'd let you know. Cheers
Kevin

We have some other bug reports like that. But currently no idea for a fix.
This might be a graphic driver issue. Please report your graphic hardware and your installed driver as well.
Thank you.

Thank you, Kevin. If this crash ever happens again, please save the Mixxx log file from ~/.mixxx/mixxx.log before you restart Mixxx and attach here.

This effects an old Version om Mixxx so we can close this now.
Please file a new Bug if this happens again with a recent version of Mixxx.
