Hi,

i use a dock for many months with an acer computer on ubuntu 24 and all is working fine.
But I bought a new dell inspiron and i encoutered bad glitches when screens are refreshing.
Its a dual boot windows11 + ubuntu, and on windows without any driver, it works fine, no glitches. So, its not a hardware problem to my mind.
My other computer with the same version of ubuntu works great also it comes from the dell computer. But how to resolve this? Can you help me please?
As to me its a refresh probleme because when a drag the mouse it refresh the part of the screen.

Thank you so much.

computer: https://www.dell.com/fr-fr/shop/ordi...ptop/bn74714sb
driver: https://www.synaptics.com/products/d...wnloads/ubuntu

I've tried to install intel graphics third party driver and wow, it was a disaster!
I've tried to install a legacy displaylink driver but same horizontal f... lines when i drag any window.
I've tried to install ubuntu 22 and....it works fine...

Any other idea to test on ubuntu 24??
