Comment 15 for bug 1782852

I've just installed ubuntu enviroment ( disclamer: on a Linux distro ) and I manage to get the issue but after tried it a lot. The simple reproduce steps didn't produced any issue.
After that I tried again for a long time with up to 4 board open in 3D Viewer and I didn't get the issue.
My GPU is about 6 or more years old and is a basic OEM NVidia that comes from desktop PC vendor.
What are your GPUs and drivers?

@Seth: Generally only polygons are triangulated on 3D Viewer. On this case, the circular pads are rendered as 2 textured masked triangles. Thats why we see it in the bug as square points, because pads are rendered as a square with a texture mask.

So it is possible that this texture is being corrupted (or outdated?) in GPU or the handler ID is corrupted on CPU.
