<pre>Description:
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.
