I guess this was merged to upstream kernels. I have no issues on 20.04 with 5.6.3 Kernel (actually since ~5.4.0 I do note experience this issue anymore).
On another note, I see a similar tearing when playing high res videos on youtube (I have 2x4k monitors connected to my XPS 13 7390 / no fractional scaling enabled). Can someone confirm this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1855608 Title: Dell XPS 13 7390 screen corruption in 18.04 LTS, 19.04 and 19.10 on Intel Comet Lake To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1855608/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
