Help with my hex editor!

Hi, I'm currently using Daxatk, a hex editor. As you can see, there's the current app locked by the editor on the upper left corner of the picture. However, when using Daxatk in my Z Ultra, the Xperia Home is being locked by the app and not the other app itself (e.g. Ragnarok Path of Heroes). I think it's because the on-screen buttons (back, home, and multitasking) are displayed whenever I play a certain game.

Can anyone give me a solution for disabling the Xperia Home app so that the hex editor will locked my currently-opened software?
