Whenever I have a LibreOffice window in a second monitor, all dynamic graphics don’t appear properly. Highlighting with a cursor or keyboard shows the current cursor placement within text, but not the group of text selected.

For example, I currently have Impress open on my second monitor and Writer open on my primary. Operating with all windows on my primary monitor is no issue, but moving just one to the second results in all instances acting up.
One example, the right-click window appears as a blank grey box:
