--- Comment #19 from V Stuart Foote <vstuart.foote at utsa.edu> ---
As in comment 14
After more experimenting, the highest resolution mode for the secondary display
which works is 1360 x 768.  Any resolution below 1360 x 768 (which includes
1280x1024) appears to work.  Anything higher than 1360 x 768 doesn't work.

So any 4K or QHD monitor/projector will cause issues when driven by LibreOffice
with "Use Hardware Acceleration" graphics mode.  Presentation at higher
resolution with CPU only rendering or OpenGL rendering do not tear.

Frederic, could test the Impress presentation using OpenGL rendering and CPU
only rendering as compared to Use Hardware Acceleration.
