pcbnew crashed when zooming in/out with hatched GND

Backtrace

I am unable to get this to crash. It looks like you have quite a few commits after the master branch. Please try with baseline master and see if that fixes the issue.

I cleaned my master branch, and recompiled. Crash is still there.

It definitely depends on the orientation angle of the hatching. 0-10 degress seem ok. 45 degreee is crash-prone.

To make it crash I need to have: Standard Graphics (F12), Preferences/Preferences/Fallbacks Graphics: Fast Antialiasing.

All other antialiasing options do not crash. Accelerated graphics seems to be ok.

Rapidly zooming in/out often crashes under a second. Once I got it to crash by just making the hatched layer invisible and visible(chrash) again.

Maybe, someone can reproduce this.

I cannot duplicate this on linux using any of the antialiasing settings on my system. I'm using the noveau drivers on my system at the moment so it could be a video driver issue on your system. If someone else can duplicate this, please chime in.
