MBP 16 screen glitches

[macos2008]

Hi,
Recently, I had a random graphical and color glitches on chrome (screenshot attached)
I have tried to disable the hardware acceleration and then it returned to normal but when activating the option the glitch come back
I have tested at the same time with Opera and I had the same issue but not with Safari. when shutting down and next day it return to normal, like only when I worked a lot with...
I am afraid that there is an issue with the graphical card since it was with both opera and chrome, perhaps that Safari is not using the graphical acceleration 😰
Have someone had this issue ?

Conf:
MBP16
I7 16G
AMD Radeon Pro 5300M with 4GB

Which graphics card was in use during this issue? Do you have any monitors attached? Please post more details about your setup.

I don't know which card was used and I don't have any monitor attached. the MBP16 is the base model

System Information will show which card under Graphics/Displays. The active GPU will show the MBP display connected.

The system showed both at that time, and even now, it's showing both
AMD Radeon Pro 5300M 4 GB
Intel UHD Graphics 630 1536 MB

Thanks. I mean if you click on a card, the active one has a display section in the box below which shows the resolution, etc. The inactive one is empty with only "Metal:" at the end.

I just find that there are others who have the same issue, looks like the majority are with the new MBP 16

Strange Chrome browser graphical glitches

Here's another strange bug I'm experiencing with the new 16" macbook pro... I'm experiencing some strange, and seemingly random graphical glitches in Chrome on certain websites when my Mac is attached to an external display. I mainly use Safari, but for work stuff, I like to use Chrome. I've...

I didn't notice that when I had the issue, but now it's the AMD Radeon Pro 5300M 4 GB

I previously had this problem regularly on Microsoft Teams and Chrome on my MBP16. After reading other advice, I disabled PowerNap and Automatic Graphic Switching in Energy Saver settings. The problem has not reoccurred since. Worth trying that.

I experienced the same thing on chrome periodically, as such I switch over to Firefox, no issue since.

Same issues here. In addition to the already mentioned glitching in chrome/electron apps, I'm also seeing bad graphics performance in games after waking from sleep. Noticeable difference in performance and tearing/glitching for example in Subnautica or Divinity OS2 through Steam.

Disabling dynamic gpu switching seems to hide/prevent the issue as mentioned, I'm guessing there is some driver issue triggered in waking from sleep.

Actually, the Automatic Graphic Switching was disabled, I just notice this. This means that it was using the AMD Radeon when I had the issue

I had the issue in Opera too, but didn't try Firefox

Hope it's only a driver issue, what I have found with interbear post, that Automatic Graphic Switching was disabled. But I don't understand why disabling the hardware acceleration in chrome make it to came-back to normal, since it should use only the same graphical card
