I applied your patch nearly as you did to st, because it seems to be the
right workaround to have some framerates in st. With your default of
30fps for x events and 5 fps for events if there is action from the tty
makes st feel sluggish.

Please try to see how much the CPU usage changed with the defaults in
the repository. I can’t really apply 5 fps; this makes output feel like
the terminal is hanging.
