Expected behavior
to not have the flicker upon opening a terminal with blur

Environment

  • Distro: [Archlinux]
  • KWin version: [kwin 6.1.4]
  • Krohnkite version: [commit: 3f52948 which added ability to ignore vdesktop (though the bug existed before that )]

The flicker is not noticeable when disabling blur in the terminals . I also Attached a video for visual reference.

I use konsole and kitty and cannot confirm the problem, try another tile script to look the problem persists. I think that the key problem may be in kwin script in general.

I'm not sure if this is related, but I have a very bad flicker when using the keyboard shortcuts to move open windows.

The screencast unfortunately does not capture the severity of the issue. In the screencast you can see a small flicker, but in reality that flicker flashes the entire desktop wallpaper underneath with full transparency making it extremely jarring and unsettling.

What terminal emulator are you using?

What terminal emulator are you using?

kitty - https://github.com/kovidgoyal/kitty

However it happens with other applications too: emacs, firefox, konsole

The flicker is always on the right half of the window.
