@lyse@lyse.isobeef.org Yep, the scrolling is part of the GUI (responding to scrollbar events, translating coordinates, nasty stuff like that). It’s pretty brute force right now because it does a full redraw for each scroll event – a faster version would be to use WinScrollWindow() which scrolls/moves existing window content and then you only draw the new parts. Maybe I’ll do that in a later version. 😅
