I’ve run into a couple issues, one that apparently is known and a second that I don’t find mentioned elsewhere. I’ll start with the second.
LibreOffice 188.8.131.52 (x64)
Windows 10, HP Zbook
The short story is that I created a 2nd user on my machine and the Tools>Options>LibreOffice>View>Graphics Output settings were configured differently. I know I installed LibreOffice on the 1st account; I don’t recall if that was before or after creating the 2nd account. However, I ran the install program>repair in the 1st account and again in the 2nd account, and the settings were different. In the 1st account, Use hardware acceleration was unchecked, and the 3 others were all checked (Use anti-aliasing, Use Skia, Force Skia). In the 2nd, Use hardware acceleration, Use anti-aliasing, Use Skia were checked, Force Skia was unchecked.
The longer story is my finding this because of the 1st issue I ran into, which is that Impress slides presenting full-screen won’t update with the settings the 2nd user had. None of the machine’s users ventured into any of these settings and it was a bear to figure out why presenting was working for one user but not another. I’ve seen a closed question indicating that disabling hardware acceleration fixes the problem, which is how the 1st user was configured. It’d be nice if the configuration for additional users worked right.
