All Atoms Turn Dark Red When Hovering Mouse in OVITO Pro

Hello,

I am experiencing a strange issue in OVITO Pro. Whenever I hover my mouse over the viewport, all atoms suddenly turn into a red color. This happens regardless of the dataset I am using. However, the atoms do not return to their original colors when I move the cursor away. Instead, they only revert to their original colors when I either:

  1. Click the Play Animation button (or press the spacebar).
  2. Click on various buttons within the OVITO interface.

I couldn’t find a similar issue in the OVITO documentation or forum. Has anyone else encountered this problem? How can I disable this unintended color change?

Any help would be greatly appreciated!

Thank you.

Thank you for reporting this error. I think it is the same bug that has already been reported here:

Could you please try these new OVITO builds to see if they resolve your issue:

Hello,

Thank you for your response.

I downloaded and ran the OVITO PRO (Windows version) you suggested, but the same issue persists.
It appears that both OVITO PRO and BASIC 3.12 versions have the same error.

For now, I have downgraded to OVITO 3.11, and the issue does not occur in this version.
If you find a solution, I would appreciate it if you could share it with me. I will also continue trying different approaches.

Have a good day!
Thank you.

We are still trying to find a solution to this issue, which occurs only on certain Windows systems. Could you please help us by testing the following new development build of OVITO on your computer? Please let me know if it fixes the issue or not. Thanks!

(Testing one of them sufficient, Basic and Pro share the same OpenGL viewport renderer.)

Hi,
Thank you very much for your effort. In my case, the bug persists in the new 12.1 dev version. I am very sorry for that.
A snapshot is attached.

Thank you, Fan, for testing this version. Yes, it is a pity that this has not yet led to any improvement, but we will continue to look into other possible fixes. It would be helpful if you could continue to assist us. Daniel and I will probably ask you again to test a new version sometime.

When you find the time, please test the following builds of OVITO Basic or OVITO Pro:

In this new version, OVITO uses a separate OpenGL context to perform the object picking offscreen rendering pass. That’s the (red & green) false-color image you accidentally see on screen, which is supposed to be invisible. Let’s see if this code change brings any improvement. Thanks.
