fcitx broken after install nvidia driver

  • i5-6400
  • HD530/P106-90

After I installed the Nvidia Driver by the hard way, the stock intel driver is not working(-> llvm pipeline). So I install the prime-select to switch the nvidia/intel/intel2 driver.
But the fcitx only shows up in GNOME, like search bar. In other application, like Telegram/Chrome, the candidate window never shows up/

GNOME Wayland?
