Created attachment 140751 [details] .jpeg image of my screen under slideshow On some screens, slideshows are messed up using Impress (see attached image). This is on my Windows 10 Dell Latitude 5285 laptop and using a QHD Dell screen. My video driver is up-to-date.
To be more precise: this happens even on a blank presentation. So this bug is not linked to the content of the presentation.
