I'm running on Linux Mint 22.2. I went from version 3.1.3 (from your get.openlp.org archive) to 3.1.7 (using a .deb file downloaded from Debian's Trixie archives, as I prefer to avoid things like Flatpaks when possible). It seems to work fine, except for a little snag when showing text over video. As soon as the video loops back to the beginning, the text disappears. I have to either move to the next slide or restart the slide to get the text back, and then have to do it again the next time the video loops. This didn't happen in 3.1.3.
