Summary: SLIDESHOW: fading slide transitions start with a white
`flash'
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: Other
Whiteboard: BSA
Status: UNCONFIRMED
Version: 4.2.4.2 release
Component: Presentation
Product: LibreOffice
Problem description:
The slide transitions `Fade smoothly' and `Fade through black' produce a white
flash (like one frame of a video, sometimes the white screen is interrupted
with black bars) before starting. The following slide is normal.
Steps to reproduce:
1. Choose a background color of the previous slide (the one from which the
effect starts from) which is different from white (otherwise the effect is
barely visible but still there).
2. Set slide transition to either `Fade smoothly' or `Fade through black'.
Already the preview shows the white flash but it gets really obvious on the
presentation
3. Look at the transition in the slide show and `flash' your audience
Current behavior:
Slide transitions involving a fade start with a white flash or burst before
operating normally.
Expected behavior:
The first frame of the transition should equal the starting slide without any
glitches.
Remark:
I have Fedora 20, on kernel 3.14.3, x64 on an Asus UX51V with NVidia+Intel card
(The intel card is active with nouveau as driver, glx active). Java, opengl,
flash, etc. work usually correct without errors.
The flash effect looks like if a non initialized page is simply displayed
before the first rendered frame.
Remark II:
I never used these transitions before, so I cannot tell when this glitch
appeared first.
Operating System: Fedora
Version: 4.2.4.2 release
