Public bug reported: 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.
