Comment 6 for bug 1782852

Was there some change in the 3D render code in last release? (list bellow)
Since than, that for me fixed https://bugs.launchpad.net/kicad/+bug/1783181, I try to reproduce the issue with the reported steps and something interesting:
1) I could not reproduce opening the second project in the 3D view;
2) But I reproduced not opening a thirty project with 3D;
3) The first 3D was not affected and the issue happens on the second and thirty in the same time.

Appear, I don't know how, after some MB of use by the 3D render motor this problem appear?

Since I can reproduce this yet, the developer want that I create some `gdb` report?
