If you have anything in particular you would like me to tweak locally to debug, I'm happy to do so.

[thlorenz]

Thanks for the details .. a core dump is pretty bad. Looks like I'm using something that's not supported on Linux yet.

One thing I could imagine is the shader I'm creating for the radar here. That can easily be disabled though.

Could you try to just set enableGradient to false here?

If that fixes it I'll create a Linux specific entry point that disables that shader properly.

The other possibility is that picture recording isn't working anymore for Linux. That can be disabled in the same area by hard coding to false to see if this fixes things. In know this worked before on Linux, but am seeing something related in the stack trace.

[kenvandine]

Close, setting enableRecording to false fixed the crash! enableGradient is fine.

[thlorenz]

Awesome .. I'll make it so that it's disabled for linux by default in the next version.
Unfortunately that may affect performance negatively (framerate will be fine most likely, but CPU usage might go up).

Odd is that the previous version had this turned on for Linux and didn't crash ... but who knows.
