turn off G-SYNC in the NVIDIA system settings
I have a problem of stuttering and getting stuck in the contract pop-up window, as well as any other pop-up window. This problem appears after working on the project in a little time from 15-20 minutes and after that I had to lock the project because I could not work and the contract window would not appear for me, so who has the solution, please help
Thank you brother, the bug has been fixed, thank you very much for the help
