impress transitions blinking

lo5, windows 8, 4gb
transitions between pages even just smooth transition changes colors, then flashes the previous screen before showing current screen. for example, my background is blue, when i click next it changes to the last screen for a split second, then new backcgound but instead of blue it is red for a half second, then flash, blue background as normal. no idea what i am missing, anybody seen this?

Possibility of the OpenGL/OpenCL bug biting you. Check it out at reply to Q64314.

It did not resolve the problem as OpenGL options are disabled by default on LibreOffice 5.
I have the same issue when trying any transition option except none (obvious).
It shows the transition, then blinks the slide.

I’m currently using Libre Office Version:
Build ID: 1:5.1.6~rc2-0ubuntu1~xenial2
CPU Threads: 4; OS Version: Linux 4.4; UI Render: default

For the record, I also observed that blinking with version 5, but it disappeared with version 6.0.
