Fusion Studio - Ubuntu / PopOS - Screen issue



I just bought a Fusion Serie and I'm having screen issue when running Ubuntu (tested 20.04 and 21.04) or PopOS (tested 21.04)
  • built-in screen display is blinking when the mouse cursor is moving within its display area using the touchpad or a mouse
  • if I press the left button while moving the cursor the display does not blink
  • when using an external monitor its display is fine, but not the integrated screen one (in duplicated or extended mode)
  • I recorded the screen and the video is not showing the blinks (although the screen was blinking while recording)
What I tried:
  • changing screens resolutions
  • enabling / disabling PopOS HiDPI daemon
  • use different kernels (from 5.11 to 5.14)
Here are the laptop specs:

Chassis & DisplayFusion Studio Series : Écran large LED mat 14 pouces 90 Hz sRGB 95 % WQXGA (2880 x 1800)
Processor (CPU)Processeur Quad Core Intel® Core® i7 11370H (3,3 GHz, 4,8 GHz Turbo)

1st M.2 SSD Drive500 Go SAMSUNG 970 EVO PLUS M.2, PCIe NVMe

And some commands outputs (from PopOS 21.04):

I don't really know which potential fixes I should start with therefore any help will be greatly appreciated.


NOTE: I also have W10 installed along side PopOS and W10 is working fine.

I have just purchased a fusion studio and have the exact same issue. I really don't want to be restricted to using windows

I've noticed that using keyboard only, the screen flickering is much less severe although still present. I also tested the latest LTS lubuntu.



Same for me.
But to me it is more a workaround than a proper fix as it does not allow to control screen brightness and does not provide full capacity of the graphic chip.

Aside from this:
- I am also not able to recover from deep sleep
- If not in deep sleep mode, sleep drains a LOT of battery
- Upon starting I am getting the following message:
dpc rp pio log size 0 is invalid

Are you also facing those issues?
