            Bug ID: 143497
           Summary: SLIDESHOW: Much slower going to previous slide than to
                    next slide
           Product: LibreOffice
           Version: 7.1.4.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress

Description:
While in fullscreen slideshow presentation mode, the slides load very slowly
when trying to go backwards through the slide deck to go back to some previous
slides. The speed at which it goes forward through the slide deck is pretty
good. I have only tested this on my current version of LibreOffice, version
7.1.4.2 release. 

Steps to Reproduce:
1.Start presentation with multiple slides
2.Go to next slide a few times (moving forward). Notice the reaction time.
3.Go to previous slides a few times (moving backward). Notice the very long
reaction time. 

Actual Results:
It was quick to move forward and extremely delayed to move backward.

Expected Results:
It should be quick to move forward and quick to move backward. 


Reproducible: Always


User Profile Reset: No
