                    hardware acceleration is disabled
           Product: LibreOffice

Description:
When a transparent image is animated with a fade-in, and hardware acceleration
is disabled, a rough cut of the images is shown during the fade-in.

It seems like the image was transformed such that it is totally transparent on
the most transparent parts and totally opaque on the most opaque parts.

See the video attached.  It happens in second 5.8.

Note that this only happens with hardware acceleration enabled.


Steps to Reproduce:
Open the presentation attached.

1. Make sure you have hardware acceleration disabled.
2. Open attached presentation.
3. Enter presentation mode.  Don't do anything, just wait.


Actual Results:
Rough cut of transparent image shown on fade-in when hardware acceleration is
disabled.

Expected Results:
Image should fade-in with the correct transparencies.


Reproducible: Always


User Profile Reset: No
