When in Calc while editing a formula (within the cell via F2) with

If the arrow keys are used to moved left and right, while moving past the
character within brackets a cursor trail is displayed like this:
SUMIFS($|T|B|_|d|a|t|a|.|C|$|8|:|C|$|3|2|,|$|T|B|_|d|a|t|a|.|D|$|8|:|D|$|3|2|,|A|3|6).
The first use of F2 editing is OK but subsequent uses display this
behavior.
When you get to the closing bracket the cursor trail disappears. Or if
you
minimize then restore the window the cursor trail disappears.
It seems to happen only within brackets, seems to be a failure to refresh
while within brackets, impacts Linux & Windows versions, and this display
error was not always present. This behavior is described in bug 67787
from
2013-08-05.
I believe it may be related to the bracket matching (high lighting)
feature
that was introduced a few years back. Does anyone recall which version
added that feature or know anything about this feature?
I find this super annoying and would like to improve the bug report. If
related to bracket matching I'd rather that be disabled versus a cursor
trail rendering F2 in cell editing useless. It also makes LO look
unpolished.
I wonder if this may be related to using OpenGL for rendering, which has
apparently been enabled by default from version 5.0.2 onwards. It should be
possible to disable via Tools > Options > LibreOffice > View. It may need a
restart of LibreOffice (including the Quickstarter if you use that) to take
effect.
If that resolves the problem, it's probably worth noting on the bug
report, along with the info about your graphics card as described at <
https://wiki.documentfoundation.org/OpenGL>. Some of these rendering
problems only occur with OpenGL, and only with certain graphics cards.
