Description R. Hutchins 2018-03-17 05:58:41 UTC
The fade transition is erratic and renders the program unusable in a professional situation.

Steps to Reproduce:
The file Flicker_Demo.odp demonstrates the problem with a show of 3 slides.

Actual Results:  
Each slide has a fade transition (through black, 2 sec. duration). Each slide flickers at the start and end of each fade. Also(although difficult to see), Slide 1 flashes for a fraction of a second while slide 2 is fading in. Similarly, Slide 2 flashes while Slide 3 is fading in.

Expected Results:
Each slide should fade out smoothly to black and then fade in to the following slide.

Reproducible: Always

User Profile Reset: Yes

Additional Info:
I'm running Windows 7, 64-bit OS with an Intel i3-4170 CPU @3.70 GHz and 8 GB RAM. The graphics are run with the onboard Intel HD chipset. Under Tools>Options>LibreOffice>View, I have tried various permutations of the "Graphics Output" options (hardware acceleration,anti-aliasing, Open GL). There may be subtle variations (difficult to see) but none are satisfactory. The flash of the previous slide is very brief; it's close to the display's refresh rate and does not always occur.

When the same file runs on an old (2009) MacBook Pro (OS X 10.11.6 with a 3.06 GHz Intel Core 2 Duo, 8 GB RAM, NVIDIA 9400M integrated graphics), the fade transitions are flawless; with or without Open GL.
