Flashing black lines in Impress

[nettie01]

Hello, I recently downloaded the LibreOffice update. I now have the flashing black designs in Impress that other people complain of. I have tried various suggestions after reading other people’s answers:

1. Try: Go to Tools > Options > LibreOffice > View and disable “Use OpenGL for all rendering”.
   (But I don’t have anything about OpenGL when I follow this instruction.)

2. I’ve tried clicking “None” for slide transition - the problem doesn’t improve.

3. I’ve tried other slide transitions - the problem doesn’t improve.

4. Someone suggested using black backgrounds - but I use a lot of art and colours and photos for my teaching presentations - of which I have more than 300, I estimate.

I would like now to go back to a previous version of LibreOffice. Someone suggested looking in the archives for the older versions (the second to last version also has flashing in Impress).
It’s not clear to me what I should click for the download. If I click x86_64/ the next pages is full of links.

Thank you for any help. I tried to attach a picture here of a screen shot.

LibreOffice now uses Skia instead of OpenGL. Click Tools > Options > LibreOffice > View and untick the box “Use Skia for all rendering” and see if that helps

IMPORTANT: You didn’t say which version of LibreOffice you have. If it is 7.1.6.2 then upgrade to 7.1.7.2, then turn off “Use Skia for all rendering”

Thank you very much! That’s fixed everything very nicely!

Have a great Christmas!
