<pre>Description:
Transitions that rely on OpenGL such as Fade, Iris and Circles do not work as
expected. Rather they show a weird flashy effect.
Steps to Reproduce:
1.Create a new Impress presentation with two slides
2.Insert text and objects in both slides
3.Apply the "Fade" transition to the second slide
4.Press F5 to start the presentation
5.Move from first to second slide
Actual Results:
The move to the second slide shows a weird effect, instead of the expected Fade
transition.
Expected Results:
I expected the Flash transition without these weird flashing of the screen.
Reproducible: Always
User Profile Reset: No
OpenGL enabled: Yes
Additional Info:
I posted a video on Youtube showing the transition effect:

My computer runs Ubuntu 20.04 and I am using the PPA version of LibreOffice. I
have a NVidia GTX 1660 video card.
I also experienced this problem in all releases of the 6.4 branch. I am also
testing the 7.0 beta 1 version and this problem keeps happening.</pre>
