De-selection does not work under some circumstances

[zhou13]

Describe the bug

Canceling selection does not work under some circumstances.

Environment (please complete the following information):

• OS: Linux X11
• Version: 20210628-091813-e05ddb17
• The active keyboard layout name: ENG

To Reproduce

Steps to reproduce the behavior.

Method 1

1. triple-click any line to select it;
2. move the cursor to another line and click.

If you act fast so that the gap between 1 and 2 is small enough, the line selected in 1 won't be deselected.

Method 2

1. press down the cursor and move the cursor to drag an area
2. move the cursor to another line and click.

If you act fast so that the gap between 1 and 2 is small enough, wezterm will always select the area of 2 rather than deselected.

Configuration

return {
    colors = {
        foreground = "#F8F8F2",
        background = "#282A36",
        selection_bg = "#44475a",
        selection_fg = "#ffffff",
        ansi = {"#282A36", "#ff5555", "#50fa7b", "#f1fa8c", "#bd93f9", "#ff79c6", "#8be9fd", "#bfbfbf"},
        brights = {"#4d4d4d", "#ff6e67", "#5af78e", "#f4f99d", "#caa9fa", "#ff92d0", "#9aedfe", "#e6e6e6"},
    },
    check_for_updates = false,
    exit_behavior = "Close",
    font = wezterm.font_with_fallback({
        "Fantasque Sans Mono",
    }),
    font_size = font_size,
    force_reverse_video_cursor = true,
    freetype_interpreter_version = 35,
    freetype_render_target = "HorizontalLcd",
    hide_tab_bar_if_only_one_tab = true,
    scrollback_lines = 35000,
    term = "xterm-256color",
}

Expected behavior

wezterm should deselect the area in 1.

How fast is fast enough for this to trigger?

[zhou13]

According to my feeling it is about 100-400ms.

[wez]

is this still an issue for you? I think we identified some other mouse binding issues that I think were probably the cause of what you were seeing here; the interaction delay is small enough that I think you were driving up the "streak" count for click counting and not triggering the event you thought you were. I'm going to speculatively close this, but please reopen if there is something still to be run down.

@wez I tested this again on wezterm-nightly-bin-20210825.094007.0fc2fdd3-1. I still encounter the same problem.

I just wanted to report something along those lines. I think the issue is that streaks are only interrupted by time or button change, but they really, really should be interrupted by significant movement.
