Slide transition flashing

In Impress, the slides are flashing as they change. How can I stop it please?

Try: Go to Tools > Options > LibreOffice > View and disable “Use OpenGL for all rendering”. Please say your operating system, the LibreOffice version and which slide transition you use.

I also have this issue.

Operating system: Linux Mint 19.1
GFX: Nvidia GTX 1060 6GB (propritary NVidia driver)
LibreOffice version
installed from flatpak flathub

And the software rendering also makes flashing.

I have been frustrated by this issue for some time. This single answer out here DOES NOT WORK!!!

I use Linux Mint 19.2 on my laptop as my primary operating system. I have been very frustrated that I cannot use my laptop to host a powerpoint presentation without crazy, black flashing in every slide transition. I tried Turning off hardware acceleration. I tried editing a slideshow and disabling animations. None of this worked.

Here is what I have found that does work.

  1. Open your presentation in Impress

  2. Select the first slide, go to “Slide Transition” on the right side.

  3. Select “None”

  4. Click the “Apply Transition to All Slides” button

You can now present a slide show without distracting, unprofessional, crazy, black, flashing between every slide!
