Prevents re-drawing when inactive to save CPU.
Fix developed by @Rangsk, posted on Cracking The Cryptic discord server.
The original script is published on github.
I've updated this one with Rangsk's version because it was causing lag on some actions. In the author's words:
I ended up writing this script instead. I wasn't happy with how unresponsive f-puzzles felt at low fps, and if I increased the fps limit it didn't really help the CPU situation.
Lowers CPU usage by preventing re-draws while no inputs are occurring.
Your CPU use should be much lower while not using f-puzzles (mouse not moving over reactive elements, not inputting things, stuff like that). There should be no noticeable difference in behavior, but cpu use should be essentially 0 if you're not actually doing anything in the active f-puzzles tab.
