Hey! I’m having this annoying problem sometimes, and the only solution I find is restarting the editor…  
Sometimes, when I press click to open the window you use to find some node in the Event Graph, that window appear in 1 frame and then just dissapear… Did you guys ever had a bug like this before? ☹ Thank you!

Looks very much like the Nvidia driver bug:

> Could you maybe write out what this fix was? The link you posted no longer works, and I’m having this same issue! From context clues it seemed to be about the nvidia colour settings, but I change from ‘default’ to nvidia and it didn’t seem to fix the issue? Do I need to do something else?

Just in case someone need it. You’ve to download a Nvidia file and run it, here’s the link 😃 [After updating to NVIDIA Game Ready Driver 461.09 or newer, some desktop apps may flicker or stutter when resizing the window on some PC configurations | NVIDIA](https://nvidia.custhelp.com/app/answers/detail/a_id/5157)
