Here is the video I recorded of my toilet: Toilet Problems
So about a month ago our dual-flush toilet suddenly stopped filling up properly. It takes forever to fill up and it doesn't even fill up properly anyway. What I have seen is that if I flush and I turn off the water supply, wait about five seconds, and turn it back on, the toilet fills up like normal and properly. If I flush again, then the water just fills up slowly again. So I'm not sure if someone could help me figure out what the problem could be. This is the first time having a dual-flush toilet and I'm not really sure what to do…

Don't worry, dual flush toilets aren't any different. It sounds like your Fill Valve (the tall thing on the left) is on its way out. You can do a new one with just big pliers & you'll need to replace the water hose from the wall to the toilet. $30 & 30-minutes, at the most, should get you back to normal. Or, call Roto Rooter if you don't do that stuff. It's common but not too predictable, every 10-years is a good preventative rule.
