This is an excellent topic, actually, and I'd like if we can to focus on the 'succeeded but glitched' area because that's the hardest to define. What does this mean? Technically, the test has to have been fully successful, but with unforeseen consequences. Well, that's easily defined for some tests (on a Pistols test, you hit your target but the gun jams or the clip falls out, bullet overpenetrates and wounds an innocent bystander, etc.) but very very difficult to define for others, like Perception!
Some of the non-critical glitch examples listed for Perception really don't work for me.
Normal glitch on Perception:"You don't notice anything important if it's not glaringly obvious
This doesn't work for me because that's not a glitch, it's just a failure.
Normal glitch on Perception:"You don't notice anything important if it's not glaringly obvious
That's not a glitch, it's a regular failure.
on a Perception test: You can hear someone sneaking up on you from the left. (He is actually coming from the right.)
This doesn't work for me, even though it's closer, because in a situation where it doesn't matter what side he's coming from, this is just a success, and in a situation where it does matter, this could be as almost as bad as a critical glitch. It's a valiant effort, though.
Crash_00's list of example is a good start.
Anyway, for me, non-critical glitches tend to lead to hilarious results that are amusing and entertaining for everyone at the table, but tend to break the tone of a serious game. One memorable example is when the team was meeting each other and the Johnson for the first time, the Elf hacker non-critically glitched a Perception or Etiquette test being made in the context of the meeting (can't remember which). I ruled that he didn't do anything to fuck up the meet, but he did become inextricably and unwaveringly convinced that the Dwarf samurai (PC) was actually Mr. Johnson and in charge of the run, regardless of what anyone else said. It became a running gag for the test of the game, with Quip repeatedly calling Smithy "boss". Because really, if a glitch is not stupendously fucking the players over or inconveniencing them, then it's embarassing or...hilarious. I often rely on equipment malfunctions, things like that. "You see the guy sneaking up on you, but then the firmware on your night vision goggles crashes."
