Comment 6 for bug 1849947

Hellon,
I have the same configuration (dell xps13 7390 and ubuntu 19.10) and I installed the kernel from drm-tip current and the issue seems to be resolved. The screen glitches don't appear anymore.

```
uname -r
5.5.0-994-generic
```
Thanks for the help.

@Jamie to install it you can go to https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/current/

then click on these links to download and install the debian packages in this order:
* linux-header-...-amd64.deb
* linux-modules...-generic-....-amd64.deb
* linux-image-...-generic-...-amd64.deb

Then reboot so that this new kernel is loaded.
