Corrupted display with FrameMaker 2019 15.0.5.838 (x64)
In testing the problem I reported in Bug where the Element Validation panel/pod is completely absent I am repeatly running the process to add and remove line numbers. This was working as expected up until after I created the aforementioned post.
Today, with 2019, I end up with a corrupted display as shown below:

Ctrl+l does not work. If the document is closed and then re-opened, the display is still corrupted.
This does not occur with 2020 with update 1 (16.0.1.817).
The only change is that I installed a Windows update first thing this morning KB5003173. There are no reports that I can see that report graphics problems related to this update.
When the link to Update 8 is working I will try that to see if the problem is fixed.
