Thank you Luboš. I invested several hours over the course of several days
trying to gain as much useful information as I could to aid in the
troubleshooting of this problem. I admit that disabling Skia rendering has
greatly reduced the frequency/repeatability of the problem, but it still does
it occasionally. I also thought my observation that under certain repeatable
circumstances it always affects the 22nd line of text first before subsequent
random lines throughout the document, but under other (also repeatable)
circumstances it always affects either the first or the second and third lines
of text before any others. That to me is a pretty interesting detail that I am
quite positive others would not have noticed because I am an exceptional
electronic technician and rank amateur programmer who has worked with a great
many others, both professional technicians and ordinary consumers, to know that
you rarely get useful or accurate information and that you have to verify
everything for yourself. At any rate, I also found clicking on the Toggle
Automatic Spell Checking and Toggle Formatting buttons as a band-aid fix. The
only thing I cannot attest to with this issue is that it also does it with the
touchpad and the keyboard arrows. For me, I have only ever experienced it via
the mouse, which is why I checked to make sure I had the most current version
of the driver and then reloaded it just in case. 

Again, thank you. I am obviously very much behind LibreOffice's efforts to
build a better office productivity platform to compete against the nameless
800-pound gorilla in the market, as well as all the other options available out
there. If it turns out that it is a bizarre driver issue, then I will admit I
raised an alarm unnecessarily, but when I am told that it only affects 5% of
users, then I know that the problem is genuine no matter what the eventual fix
is and I was not wrong in bringing to everyone's attention. I felt I was being
dissed by being told that it was a trivial problem and won't be addressed. I
never asked that he drop everything to work on it or that it would be easy to
find it, but there is a big difference between can't and won't. The latter term
nearly made me uninstall LO, but I was hoping someone else would at least give
finding the problem a try. I know that is why I got into the profession. Using
my talents and technical competency to identify and fix problems is the
challenge that drives me--not routine issues that are easy to spot and fix.
