I decided to replace 18.4 LTS with 19.10 and so far it has been pretty smooth. However, there is one issue which occurs frequently whereby the display flickers and becomes unusable. The best way to describe the appearance is that the image becomes heavily distorted. Sometimes it only happens for a split second, other times it is permanently distorted. When this happens, simply closing the laptop lip and re-opening seems to put the display back into it's correct state. I didn't experience this issue on 18.04 LTS which is why I believe it's a Software Bug within 19.10.
