Got it, though I'm not sure the optimal fix - basically, the problem is that when a Paint takes more than info_update_freq_ milliseconds then every single event causes a Paint (because just the last Paint took enough time to trigger the timer). I will dig further

What happens if you disable antialiasing in the overlay or set its
opacity to 1.0? I can't duplicate this (to any appreciable level, at
least) on any of my test machines.

No change - the splash is marginally faster in general, but it still slows down substantially when the window size is changed. I suspect it's some condition that is accidentally disabling the "Only update every splash_register_freq milliseconds" check, I will try and debug further.
