Regression

It appears to be the case, though I'm not certain. I saw this before several months ago, and it went away. It's come back again in the last couple weeks, but not sure if due to a new Hyprland version or config change.

Describe the bug

I thought this problem went away but started noticing it again recently... if FCITX is loaded, if I switch workspaces, sometimes keyboard input doesn't work. If I use the keyboard before switching workspaces, it works in the next one. I think the focus gets left behind or something because I sometimes see what I typed on the other workspace. Problem goes away if FCITX is unloaded.

Reproduction steps

Not easily reproducible in a predictable manner. Sometimes doesn't happen at all, but once it starts happening, it happens with every workspace change. As mentioned, unloading FCITX makes it go away.
