Maybe related to Bug #1483015 ?

I can confirm.

Using video.kicad_pcb:

In debug mode, I have error messages like:
- run out of memory
- vertex allocation error
- gpu error
Even without using the GAL mode, in legacy mode, there is also a crash just when trying to make invisible a copper layer.

With a older version ( I still have a copy of version 6016) it does not happen.

Version 6056 worked fine for me without hang or crash.

[jean-pierre charras (jp-charras)]

Version 6055 crashes for me on exit.

I checked V6056 again. It seems to crash sometimes, when I close the PCBNew window with OpenGL view enabled. V6077 was crashing almost every time, even when switching to the old canvas before closing the window.

Can you test with revision 6089?

[jean-pierre charras (jp-charras)]

In rev 6090, I do not have the crashes I had previously with my large test boards.

Thanks.

[Benjamin Kohl (ben-819)]

Rev 6089 seems to work fine so far!
Thank you.
