Ubuntu – Ubuntu 20.04 – Display glitches after wake up

graphicsnvidiasuspend

Since installing Ubuntu 20.04 last June, I was getting some glitches after monitor's wake up and those were going away after just passing the mice cursor in it. Note that those graphic glitches are very specific because I'm getting them only on my 2nd monitor which has Google Chrome open.

Since about a week now I'm noticing that those glitches are still on the 2nd monitor and my Chrome's tabs but now I can't just pass my cursor on it to make them going away. Those are way more pronounced than before and the only solution is to close my Google Chrome and open it again.

This is not a huge deal but I was wondering if anyone is experiencing the same thing ?

OS: Ubuntu 20.04.1 LTS
Graphic: Nvidia Geforce 970 GTX , Nvidia 440 driver (Same driver since I initially installed Ubuntu)

Edit: I also notice the glitches seem to be there when the computer was actually in deep sleep.

Cheers!
Xzi.
