Black rectangle (Ubuntu 18.04)

[Mihal9]

Hello,
I have a laptop with Ubuntu 18.04 and NVIDIA GeForce GTX 1650.
After I run OBS Studio (27.2.4), select "Window Capture (Xcomposite)" and choose the window I need, I get a black rectangle.
Please help me solve the problem.

Tried the same on my Acer Nitro 5 with GTX1650, got lot of crashes and black screen with any of the three available NVidia driver. So i uninstalled them and took the opensource Nouveau, here Xcomposite is able to record the screen.
