This is a graphics card compatibility issue, and the current beta version has fixed this bug. If the V1.1.0 version is not working properly, please leave your email address, I can send the test version to you.
Same here. After updating Nvidia graphics and Intel graphics to be safe, it works. Please restart your system after the update and reopen ChitTuBox. I had to manually add ChiTuBox to Nvidia by the way.
