tmux mouse mode doesnt reliably select panes

[yonilerner]

When tmux mouse mode is enabled, selecting panes with the mouse is not reliable. Sometimes clicking seems to do nothing, or lags into a selection mode. Ill attach av video to demonstrate. I have noticed that sometimes clicking fairly quickly in quick succession (slower than a double click) will be more reliable

cursor-style-blink=false
shell-integration-features=no-cursor

keybind=global:cmd+opt+t=toggle_quick_terminal
keybind=cmd+right=next_tab
keybind=cmd+left=previous_tab

could you perhaps use the terminal inspector to view the mouse states? (and post a video here)
Tmux might have some odd behavior on how its reporting mouse events in mouse mode

I didnt see anything interesting here but Im not sure what to look for

I've noticed similar behavior to @yonilerner. It looks like in the provided screen capture, the "Click State" on the right side of the inspector is "R". Right clicking once in the terminal fixes this. It seems like there's some way for the right mouse button to be stuck in a mouse-down state (maybe when it's used with a modifier key?).

I've encountered this behavior both on macos and Linux (Debian 13, GNOME 48).

I am late to the party, but what $TERM is being used for tmux sessions?

Tmux (depending on your config and overrides as well as versions) doesn't always play nice with xterm-ghostty.

Popular opinion for tmux seems to converge on setting your $TERM value to xterm-256color, you may try that as well.

My experience was with TERM=xterm-ghostty and tmux 3.5a. I was originally using TERM=xterm-256color but ran into other issues (it was a while ago, I don't remember the details).

The $TERM value outside Tmux should be xterm-ghostty, and the $TERM value inside Tmux should be tmux-256color (preferred, I think) or xterm-256color, if I remember correctly.
