DECSTBM reset to full screen
DECSTBM with no parameters (
ESC [ r) resets the scroll region to the full screen. After reset, scrolling operations should affect all rows. Applications use this to restore normal scrolling behavior after using scroll regions. Failing to properly reset can leave the terminal in a state where only part of the screen scrolls, causing rendering corruption for subsequent applications.How this is tested: Set DECSTBM 5;10, then send
\x1b[r (no params), write 30 lines, verify full-screen scrolling works (total lines > screen height).Analysis2026-03-26
