Yes I have no idea why that problem exists, in some computers it looks fine and on some it doesn't. I think it's some bug with flash so I can't really fix it, but I added an option on the top right of the screen to change the background color so just use that and you should be able to read the text.
 "Gems Idle"){kind=icon}
 "Press The Button"){kind=icon}
 "Idle Life"){kind=icon}
 "Project Restoration"){kind=icon}
 "Idle Goo"){kind=icon}
 "Idle Necromancer"){kind=icon}
