Hi @head77x,

Have you tried:

  • Restarting your browser
  • Restarting your computer
  • Trying a different browser

Yes, right. Try on Safari, chrome.
So I’m now trying to delete Chrome and reinstall it.

I reset everything but still have the same problems.

Does this happen on any PlayCanvas example? Or on a specific project?

Also can you try a non PlayCanvas example, e.g. three.js examples
