KDE Plasma 6 shell - desktop freezing

MC 1.19.2 Forge with FPS Monitor 1.3.0 on KDE Plasma 6 X11 can result in the shell becoming unresponsive.

It seems to correlate to rapid changes in memory usage, which can be the case when using large modpacks with optimization mods.

I've confirmed that the window title is to blame: setting `game_window_info = false` in `fps-client.toml` seems to solve the problem. I haven't taken a look at your code but if you're using callbacks or interrupts then I'd recommend switching to fixed-interval / cooldown approach for title changes.

Start by tracing the implementation behind `game_window_info` in `fps-client.toml`, focusing on how window-title changes are triggered. Reproduce the freeze on KDE Plasma 6 X11 while memory usage changes, then verify that the shell remains responsive and the option still controls title updates.
