Hi,

After updating to 3.12, I came across an issue ( I think that’s an issue):
When I open one file, it will look like:

And When I click anywhere or do anything with my mouse, it will look normally:

Thank you for this report. This looks like a bug. Just to confirm, this happens with all files you load, or just specific ones? And once you interact with the program the visuals go back to normal?

Hi,

sorry for the delay to reply. For youe reference:

  1. I tested several files and the issue always happened.
  2. Yes, it would be normal when I did any interaction.

Now I go back to an older OVITO version and the issue doesn’t happen, therefore it’s quite possible that it’s a bug.

Thank you for the update. We had 2 or 3 reports of this bug. So it appears to be quite rare but we’re investigating the issue. I’ll let you know once we know more.

I’m unable to reproduce this issue locally, so it appears to be quite system-specific. I’ve prepared an update that will hopefully resolve the problem. You can find the development versions here:

It would be great if you could test them on your system and let me know if this resolves the error.
