[nvidia-390 + GeForce GTX 750 Ti] After bionic upgrade: Corrupted, illegible text/scrollareas in apps like update-manager, gnome-calculator, …

[Benjamin Schmid]

I upgraded from xenial to bionic and now experience issues with illegible, distorted textfields / textareas or scrollareas in a set of specific applications.

For example:
* The change log field on prompting for security updated or the list of software sources in the update-manager application
* The textfield for entering the equations in gnome-calculator

I'm not having any problems i.e. with Firefox et. al.

I'm using a NVIDIA 750GTX with the officially bundled nvidia-driver-390.
