(Solved) Linux LibreOffice Impress flickers when displaying slides

edit

It could be this bug.

You can also search for yourself in Bugzilla:

Make sure there's nothing overlapping your videos (e.g. text boxes) and that your videos aren't placed on the edge of the slide. That helped for me

Hi, had the same issue.

Apparently there is a workaround to minimise flickering.

Go in Tools > Options > Libreoffice Impress > General and uncheck Use background cache

It worked for me.

I use Linux Mint too with Nvidia Gt1030 graphic card. Which version of LO do you use ?. Could you tell us some details about your graphics card, is it dual screen ? driver used (nvidia / nouveau / intel HD graphics / etc ) ? VGA/HDMI output ? I noticed nothing about this. Do you use transition animation between slides ? If yes, try to desactivate them.
