I updated my Dell Precision 5540 firmware today with
sudo fwupdmgr update.
The update was to 0.1.6.0 and it fetched from fwupd.org
The laptop uses a hybrid graphics setup and has an Nvidia quadro T2000 that is not enabled.
I noticed that now in certain 3rd party applications such as signal, typora, slack etc. I now have incredibly bad screen tearing and also strange horizontal lines on the dropdowns.
I do not think issue is not related to my Nvidia graphics driver but rather the integrated Intel graphics.
Below is some info I think could help:
lspci -nn | egrep -i "3d|display|vga"
