Turn off MMU, most games don't need it (the ones who needs it will enable the setting automatically) and it will bring performance down. For the graphical glitches, keep Bounding Box enabled as it's an requirement for the Paper Mario games, if you disable it you'll encounter all sorts of graphical issues and even softlocks under some circumstances. Disabling "Store EFB Copies to Texture Only" should fix the glitch shown on the screenshot but will likely make the game slower too.
For the performance issues, it might not be avoidable at the moment (especially on Android). Bounding Box isn't exactly cheap to emulate (it gets exponentially worse at higher internal resolutions), but you can try switching from Vulkan to OpenGL (or vice-versa) if you haven't already, to see what performs best on your phone...
