As the title, I have been experiencing pink mesh in weight paint mode every time I try to rotate/pan the view using the middle mouse button.
What I did:
1. Select mesh object and go to weight paint mode
2. Select a bone - weights of the bone shows correctly
3. Try to rotate/pan the view - weight becomes pink as if it hasn't been parented
4. Reselect the same bone - weight shows correctly again
From the gif, you can see that the hand and the clothing are two separate objects parented to a single armature. However, the problem only appears on the clothing and not the hand. For the hand I can rotate/pan the view without problem.
Any insights on the cause are greatly appreciated!
