This just started happening within the past two weeks. When I open a PDF in Zotero and switch to fullscreen mode while in landscape view, the bottom of every PDF page gets clipped (by about 4cm when an A4 sized page is opened). This is happening on a Tab S7, Tab S9, and an S23. Fullscreen works fine if I start it in portrait mode and then switch to landscape. However, if I do this, then switching out of fullscreen while in landscape will now put too much space between pdf pages.
