patch 9.2.0259: tabpanel: corrupted display during scrolling causing flicker
Commit: https://github.com/vim/vim/commit/f6e1dd11f45e555710cf202a06af15b8f823e609 Author: Yasuhiro Matsumoto <[email protected]> Date: Thu Mar 26 21:03:46 2026 +0000 patch 9.2.0259: tabpanel: corrupted display during scrolling causing flicker Problem: tabpanel: corrupted tabpanel during scrolling causing flicker Solution: When the tabpanel is visible, force a line-by-line redraw in win_do_lines() similarly to popup handling (Yasuhiro Matsumoto). When a vertical tabpanel is visible, terminal scroll operations in win_do_lines() affect the full screen width, corrupting the tabpanel area. The tabpanel is then redrawn via redraw_tabpanel, causing visible flicker. Return FAIL to force line-by-line redraw instead, analogous to the existing popup_visible check. closes: #19832 Signed-off-by: Yasuhiro Matsumoto <[email protected]> Signed-off-by: Christian Brabandt <[email protected]> diff --git a/src/screen.c b/src/screen.c index 78927c163..eeee319bf 100644 --- a/src/screen.c +++ b/src/screen.c @@ -3845,6 +3845,13 @@ win_do_lines( if (!no_win_do_lines_ins) clear_cmdline = TRUE; +#if defined(FEAT_TABPANEL) + // Terminal scroll operations affect the full screen width, which would + // corrupt the vertical tabpanel area and cause flicker. + if (tabpanel_width() > 0) + return FAIL; +#endif + /* * If the terminal can set a scroll region, use that. * Always do this in a vertically split window.
