acm popup menu not align well with cursor on KDE plasma 6 wayland

[eval-exec]

I am running KDE Plasma 6 on a HiDPI screen with a resolution of 3840x2160. I am using Xwayland to run Emacs, and the completion menu in the lsp-bridge does not align properly with the current cursor position.

lsp-bridge version: * ac40260 - (HEAD -> master, origin/master, origin/HEAD) Add new option acm-backend-lsp-block-kind-list (18 hours ago) <Andy Stewart>
system: "x86_64-linux"
host os: Linux 6.8.6, NixOS, 24.05 (Uakari), 24.05.20240416.5672bc9
DE: KDE Plasma 6.0.3
WM: KWin (Wayland)

What environment variables or configurations can affect the position of acm-popup-menu?
What information should I provide to help analyze this issue?

Thank you. 💙

You can take a look at

lsp-bridge/acm/acm.el

Line 677 in ac40260

(setq acm-menu-frame-popup-position

here

Did you use a centering plugin like olivetti?

I didn't use `centering plugin like olivetti or writeroom-mode.

If I hack acm-frame-get-popup-position to this, only change

(cons (+ x window-left)
          (+ y window-top offset-y))

to

(cons (+ x window-left 88)
          (+ y window-top offset-y))

then the popup menu looks align well...

(defun acm-frame-get-popup-position (frame-popup-point &optional line-bias)
  (let* ((edges (window-pixel-edges))
         (window-left (+ (nth 0 edges)
                         ;; We need adjust left margin for buffer centering module.
                         (/ (- (window-pixel-width)
                               (window-body-width nil t))
                            2)))
         (window-top (nth 1 edges))
         (pos (posn-x-y (posn-at-point frame-popup-point)))
         (x (car pos))
         (y (+ (cdr pos) (* (or line-bias 0) (line-pixel-height))))
         (offset-y
          ;; We need move down to skip tab-line and header-line.
          (if (version< emacs-version "27.0")
              (window-header-line-height)
            (+ (window-tab-line-height)
               (window-header-line-height)))))
    (cons (+ x window-left 88)
          (+ y window-top offset-y))))

What do you think using (window-absolute-pixel-position) to get the acm-frame-get-popup-position?

上面是我的截图， 你的Emacs不支持svg图标渲染， 还是你禁用了图标？
