Description NarayanAras 2021-08-21 05:10:20 UTC
Description:
In slideshow mode, when we go to the next slide, horizontal bands flicker across the screen. Mostly only one band appears, near the top of the screen. The band disappears in a fraction of a second.

The band only appears when the slide transition is happening. 

Such bands do NOT appear when I press the DownArrow key to animate the slide (e.g. when a numbered list is animated by 1st level paragraph). 

These bands have approximately 1" height, and they span the full width of the screen. They are always filled with a fixed black-and-white geometric pattern that looks like a QR bar code pattern.

This problem occurs in both the latest stable version of LibreOffice (7.2.0.4) and the latest Alpha nightly (7.3.0.0).

This is a highly annoying problem: It creates a horrible impression of the presenter!

Steps to Reproduce:
1.Make any presentation in slide show mode.
2.Press downArrow to progress through the presentation.
3.

Actual Results:
A band flickers during slide transition moment, and disappears in a fraction of a second.

Expected Results:
The band must not appear.


Reproducible: Always

BTW I am using an Acer Aspire A315-53 laptop, with 12 GB RAM

Processor: i3-8130U CPU @ 2.20GHz, 2208 Mhz
Installed Physical Memory (RAM)	12.0 GB
Available Physical Memory	6.18 GB
Total Virtual Memory	13.7 GB
Available Virtual Memory	6.75 GB

So I guess this problem is not due to a shortage of system resources.
