Hello,
Thank you very much for sharing the issue and I am very sorry about the experience!
Unfortunately, from the description, I cannot form a proper picture of what is causing the issue under the hood. I am wondering if you can share a bit more information in order to remove some of the potential culprits:
- Can you share the specification of your computer? Which operating system version are you using?
- I would like to make sure all the drivers, especially the graphics card driver, are up to date.
- How did you open the 3D window?
Looking forward to hearing from you soon!
Best regards,
Minh
