Created attachment 1141096 [details] the glitches (1) Description of problem: When ncurses uses a tab to position cursor, vte sometimes (when the tab is past all non-blank characters on the line) clears the space with background color. It's unexpected as the terminfo does not have xt (dest_tabs_magic_smso) property. Version-Release number of selected component (if applicable): vte291-0.40.3-1.fc22.x86_64 gnome-terminal-3.16.2-2.fc22.x86_64 How reproducible: In LE editor with certain files and cursor position. Steps to Reproduce: 1. Open a file in LE 2. Position cursor on a tab stop near the line end 3. move cursor up/down Actual results: see the photos. Expected results: no glitches on the screen Additional info:

Reported upstream: https://bugzilla.gnome.org/show_bug.cgi?id=764330
There's a patch in the upstream bug, could you please test it with LE and let us know the results? Download latest vte-0.44.x tarball; untar; apply patch; ./autogen.sh --without-pcre2; make; ./src/vte-2.91 => try within this test emulator
Could you please provide *concrete* steps to reproduce the problem?
Created attachment 1142086 [details] cat the file to terminal to see the problem To reproduce the problem, output this file to the terminal. If the bug is present, you will see cyan coloured glitches (compare with xterm).
Thanks; based on this I can confirm that the two upstream patches fix this problem. (Alas, there's a new one triggered by LE in vte >= 0.44: https://bugzilla.gnome.org/show_bug.cgi?id=754596#c15)
