I have a nVidia Quadro K5200.
I have just installed Ubuntu 20.04 LTS.
The computer works fine and recognized dual monitors.
The problems is: the screen gets flicking and shuffle when I do some activities.
When I open a document using Leafpad and scroll the toolbar the lines gets mixed, some lines gets broken image.
The problems is the video driver.
It still occurs when I open PcManFm with many icons.
Using Gimp it occurs very much! (I can’t edit any image).
prints screen: flicking — ImgBB
If I use Gedit instead Lfafpad the flicking does not occurs.
I tried to install Xorg driver instead nVidia 460… but Xorg drivers my computer gets too bad. Trying to play CS:GO is worse, the game gets slow FPS.
Ubuntu 18.04 did not have this issue.
