Any tips for creating memes using FOSS. I made this in Impress, then copy-pasted it into gimp, and it reduced the quality a lot.

In PowerPoint, you can just select everything, then right-click -> save as image, and it saves whatever you have selected rather than the whole slide. There doesn't seem to be a way to do that in Impress, but I realised you could copy-paste into Gimp and that would copy the objects as an image, so I've been making memes that way.
