any news / ideas about this?

After Rhino5 started acting weird on me (viewports freezing in OpenGL mode, dialog content shifted 90% out of the forms canvas on the first draw call,...), I can now confirm that a simple uninstall/reinstall cycle doesn't fix the GH problem.

Hardware probably isn't the problem. Only thing that is consistent is the "i7" part of the CPU name.

rest of my specs:

intel i7-2600K @ 4,2GHz

ASRock P67 Extreme Gen3

16Gig Dual-Channel-RAM

Hi everyone, I just wanted to share my 'exploding gumball' experience:

Whilst pushing kangaroo to the limit, [manipulating meshes with random vectors and springs from lines], i have pushed the engine a little too far, causing the mesh to explode/disintegrate/disappear to infinity -- sometimes when this happens, my rhino gumball disappears, or sometimes just loses its arrowheads, and whatever geometry i have in my  view-port glitches in and out of visibility during a rotate or something. This has happened a few times, if saved, it seems to corrupt the file, to recover the geometry i will export or copy it into a new file,  this has occurred on various computers running various hardware setups [i5-6series with quadro, i7-7700k w 1050ti]

for me it is not really a problem, i love the software, and understand that it will have some limitations etc.. cheers aki
