The xterm.js WebGL addon has known rendering bugs with reverse-video
(inverse color) ANSI sequences — exactly what tmux uses for its status
bar, pane borders, and selected text. On desktop the WebGL addon loaded
successfully, causing characters to render as black-on-black and appear
to 'disappear'. On mobile WebGL typically fails to initialize, so the
terminal silently fell back to the DOM renderer which handles these
color attributes correctly.
- Remove WebGL addon loading and its cleanup logic
- Remove unused xterm-addon-webgl import and dependency
- DOM renderer is the default and correctly handles all ANSI color
attributes including reverse video
