fcitx5 not work well under full screen

[aimixsaka]

• Brief in many places(alacritty, and some other electron applications), when i comes into full screen mode(use $Mod f in my bind) and type some chinese, there is no panel pops up, while out of full screen mode, candidate box woks well. (in firefox and telegram fcitx5 works well even in full screen mode)

• system

  • fcitx5 5.0.21
  • fcitx5-gtk 5.0.21
  • fcitx5-chinese-addons 5.0.21
  • Hyprland build from wiki one

• additional

  • tried both in nixos-unstable and archlinux with Hyprland, same issue(and have attempted many different fcitx5 and fcitx5-gtk version)
  • the same environment, and change from hyprland to sway, then fcitx5 work well under full screen
