I'm experiencing a bug with single word selections when the floating "Text" popup is open. After tapping the speaker icon, I try to mark the next word, but the page half-autoscrolls backwards from under my pressing finger (direct tap/long press, no dragging, I swear

). Notably, this only happens with short text selections, not whole lines, but it's annoying for foreign-language learners. It happened to me with both EPUB and PDF.
Technically, the tap zones should be disabled by setting them to "Do nothing", and reducing them to 5% screen real estate. I'm in book mode. But, so far nothing helps except switching to 1-tap text selection, and that's not precise enough, even on a large 8'' screen.
Beyond that, Librera is definitely a great find for text-to-speech & general reading on Android, especially PDF (very fast search) and DjVu (displays WinDjView bookmarks/outline, who would've thought it possible!). I have yet to find anything (else) wrong with it... LIT & PDF catalog support would be great
