    Fixed in #9675 - on windows the OmO postinstall was ran on each startup. In new release you should see a significant improvement

    on opencode 1.1.53 and oh-my-opencode 3.2.3, it still takes 3.5 seconds to load opencode in terminal

    Can we remove the windows label or add mac os too? For me it is 5s for input box to load and logs don't help much. It was waaay quicker one or two weeks ago.

    This isn't just windows, it's like that on macos also. Using ghostty takes almost 10 seconds to load. Wezterm is much faster but still noticeably slower since their last big update.

    please also add linux label or remove windows label, while faster than 20s 3.5s still takes bit of time:

    @hijoe @mfattakhov @scratchmex Are you using the opencode system theme? I switched away from the system theme and the sluggishness went away immediately. The mismatch is likely in functions like getTerminalBackgroundColor:app.tsx:44-102

    It can't all be here, as the timeout here is only 1 second, but I think there is a mismatch between the escape sequences that ghostty sends and what we are expecting. Let me know if switching themes resolves your issues as well.

    I can confirm switching away from the system theme cuts the loading time in a bit more than half. Insane. The time from clear screen to the TUI render now is faster. Still slow overall

    The root issue is in the interaction between the getPallette function in opentui and ghostty. Here are the different responses to this command in ghostty and wezterm:

    ghostty:

    ^[]10;rgb:cdcd/d6d6/f4f4^G^[]11;rgb:1e1e/1e1e/2e2e^G^[]12;rgb:f5f5/e0e0/dcdc^G%

    wezterm:

    ^[]10;rgb:cdcd/d6d6/f4f4^[\^[]11;rgb:1e1e/1e1e/2e2e^[\^[]12;rgb:f5f5/e0e0/dcdc^[\^[]17;rgb:5858/5b5b/7070^[\^[]19;rgb:cdcd/d6d6/f4f4^[\%

    We see that ghostty gets back 10, 11, 12 (foreground, background, cursor), but does not return the 17/19. However neither of them return 13, 14, 15, 16, all of which are expected from special colors to return cleanly:

    class TerminalPallette implements TerminalPalletteDetector {
  ...
  private async querySpecialColors(timeoutMs = 1200): Promise<Record<number, Hex>> {
    const out = this.stdout
    const inp = this.stdin
    const results: Record<number, Hex> = {
      10: null,
      11: null,
      12: null,
      13: null,
      14: null,
      15: null,
      16: null,
      17: null,
      19: null,
    }
    ...

    This should lead to both wezterm and ghostty hanging, but there is a backup idleTimer that times out after 150ms of inactivity (no escape sequences). Ghostty has a really chatty protocol, although I haven't looked too closely into why:

    I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[I\x1B[

    It sends a continuous stream of these escape sequences, preventing the inactivity timeout from triggering.

    The fix is in opetui, changing the timeout logic to only reset if the results table has been updated in the allotted time. It does not reset on unrelated escape sequences.

    @MaxDillon are you just using the record feature in zeterm to dump the ansi? or is it just cat tty device dump

    @CypherpunkSamurai I used the command listed at the top of my comment:

    stty -echo -icanon min 0 time 5
printf '\033]10;?\007\033]11;?\007\033]12;?\007\033]13;?\007\033]14;?\007\033]15;?\007\033]16;?\007\033]17;?\007\033]19;?\007'
dd bs=1 count=512 2>/dev/null | /bin/cat -v

    for asking for reported colors.

    The ESC [ I escape sequences, however, turned out to be the real issue as discovered in my fix here
    anomalyco/opentui#765

    Those I got by logging the buffer data directly in the onBuffer function in opentui

    export class TerminalPalette implements TerminalPaletteDetector {
  private async querySpecialColors(timeoutMs = 1200): Promise<Record<number, Hex>> {
    ...

    return new Promise<Record<number, Hex>>((resolve) => {
      let buffer = ""
      let idleTimer: NodeJS.Timeout | null = null

      const onData = (chunk: string | Buffer) => {
        buffer += chunk.toString()
        ...

    I'm running into this on Windows, startup time is 11 seconds. I'm on 1.17.9, using Windows Terminal app.
