TorReader PDF v2.2.3

Large-file rendering overhaul + rotated-page markup

Opens 200–300 page large-format (A1) CAD drawing sets smoothly — the render pipeline is rebuilt around progressive, interruptible slices plus a two-layer (memory + disk) cache, so pages never freeze the UI and RAM stays flat. This fixes the 2.2 regressions (missed pages in single view, severe lag in continuous scroll).

Fixes & features

• Markup on rotated pages (/Rotate 90/180/270) now lands in the correct place; the Arrow tool keeps its arrowhead; sticky Notes are selectable and upright.
• Text markup: reads horizontally, the box fits the text, and font size + colour are adjustable via right-click → Properties (which now shows the markup's real current values).
• Move + Undo/Redo for text/note markup.
• Blocking update dialog for new releases.
• Linux: AppImage rebuilt for broad compatibility — runs on Ubuntu 22.04, 24.04 and newer (glibc 2.35+).

Heavy CAD pages (millions of vector ops) still take ~2–3s for the first full render — a physical ceiling shared by every PDF engine — but navigating the whole document stays responsive.
