emacs 30.2, my screen is flickering, both linux and macos

[getong]

my config:

(use-package zoom
  :straight t
  :config (custom-set-variables '(zoom-mode t))
  (defun size-callback ()
    (cond
     ((> (frame-pixel-width) 1280)
      '(90 . 0.75))
     (t
      '(0.5 . 0.5))))
  (custom-set-variables '(zoom-size 'size-callback))
  (custom-set-variables
   '(zoom-ignored-major-modes '(dired-mode markdown-mode))
   '(zoom-ignored-buffer-names '("zoom.el" "init.el"))
   '(zoom-ignored-buffer-name-regexps '("^*calc"))
   '(zoom-ignore-predicates '((lambda () (> (count-lines (point-min) (point-max)) 20))))))

Here is my screen shot. If I disable this zoom config, it does not flicker.

Does this also happen with Zoom only? That config cannot justify the flickering of course, so I cannot reproduce the issue. There must be some kind of conflict with some other mode.

[getong]

(use-package auto-dim-other-buffers
  :straight t
  :diminish auto-dim-other-buffers-mode
  :init
  (add-hook
   'after-init-hook
   (lambda ()
     (when (fboundp 'auto-dim-other-buffers-mode)
       (auto-dim-other-buffers-mode t))))
  :config (set-face-attribute 'auto-dim-other-buffers-face nil :background "#42444C"))

I also use this, but only I disable zoom, it works.

[cyrus-and]

You use a bunch of other modes it seems, I cannot help you unless you provide some minimal config that reproduces the issue.

I have test shell, term, eshell, and eat command, only vterm command makes it flickering, it might be vterm + zoom bug

my vterm config:

(use-package
  vterm
  :straight t
  :defer t
  :when (memq window-system '(mac ns x pgtk))
  :bind
  (:map
   vterm-mode-map ("C-y" . vterm-yank) ("M-y" . vterm-yank-pop) ("C-k" . vterm-send-C-k-and-kill)

I'd need a standalone and minimal Emacs config with Zoom and other conflicting packages in order to help you... I use vterm all the time with Zoom and I have no issues with it.
