display glitches report #339

Closed crixthegreat closed 3 years ago

crixthegreat commented 3 years ago

hi guys,

I got a very strange display glitch to report. Here are the screenshots.

1 2 3

The green lines flicker.

This happens when I run the program with my new laptop Lenovo T14.

I wrote the program on my last Laptop Microsoft Surface Pro5, which run with nothing wrong.

The version: Python: 3.6.8 cocos2d: 0.6.7

The laptop T14 video card: Intel UHD Graphics NVIDIA Geforce MX330

I've checked that the latest driver has been installed.

Please anyone can give me some advice?

looks like a driver problem to me.

Intel integrated gpu usually have bad OpenGL support.

Can you make sure your program uses the NVIDIA gpu?

Thank you very much. According to your advice, I managed to change the default GPU to NVIDIA.

The problem is solved.
