I have just installed Eclipse IDE for Java Developers, Version: 2019-09 R (4.13.0), Build id: 20190917-1200. I have an issue with the editor when I type text into any type of text file (e.g., *.java, *.txt). As I type characters, the entire line I am editing will disappear (change to the background color) for a second or so. If I type at a normal speed (more than one character per second), the line stays hidden until about a second after I stop typing. Usually, although occasionally the line stays hidden even after the second passes. The line always re-appears if I mouse-click on a different line, or if I hit Print-Screen to try to get screen shots. I was able to get some delayed action screen shots that show the results.

In image 1, I need to add a semi-colon at the end of a line. In image 2, I have hit the semi-colon key, and the entire line disappears (and is replaced by the background color). In image 3, about a second has passed and the semi-colon (and remainder of the line) has re-appeared.

Initially I thought that this was an issue with my NVIDIA drivers, but the same behavior occurs when I run using my on-board Intel video chip. In the screenshots I have vwrapper installed but the issue occurs even after I uninstalled vwrapper and re-started. It occurs whether Smart Line Insert is enabled or notHas anyone seen this behavior and have any suggestions on how to resolve it?

Here are the outputs of some commands showing my setup. What other listings would be useful?
