Interesting! I thought for sure you were running Auto Internal Resolution!
So, you have a lot of random settings on! So, let's start with portable.txt. Place a text file named "portable" next to Dolphin's EXE. This will make Dolphin not use your settings and create new local settings directory that are just defaults (until you delete the portable.txt). Now that you've done that, without changing *any settings*, run the game you'e been testing with and see if pressing Tab to speed up the game still doesn't work in fullscreen.
