Long-time *nix user, first time Fedora user. I recently got a new work laptop (Dell XPS 7390) and have been having a horrible experience getting any distro to run on it. Horrible graphical glitches in Ubuntu 19 (On GNOME, XFCE, with gdm, with lightdm, etc.) , inoperable wifi on Elementary 5.1 (even with backported Killer drivers), etc. I ended up on Fedora 31 because it comes by default with one of the newest kernel releases. And I had tracked most of the problems that I was having to the *buntus having older (<5.0) kernel versions. Apparently the Comet Lake i7-10710u in the XPS 7390 and its associated display and wifi modules are not supported in older kernels.
However, I’m still having minor graphical issues in Fedora. See photo attached. Anyone have any tips? Currently running stock Fedora 31.
This also doesn’t show up if I take a screen shot.
