It could be a bug in the new driver

[Vea]

The A750 graphics  I'm using would have a black screen after a few minutes of running the game when running dota2. I reinstalled the driver and reinstalled the game, but it didn't solve the problem.

The system I am using is win11 and the graphics driver version is 4255.

Go to settings->video->render API

If it is set to Direct3D9 (default), then change to Vulkan or Direct3D11
