Summary	08891: trivrus: Most of the game's graphics dissapears when there's text in Jestbook and Funny Question Game
Description	This might be related with too many sprites since any letter from the texts in both modes are individual sprites, if you can put it like that. Also, i'm sure this wasn't a problem in some older MAME version. i forgot which version started to have this problem. As for the Funny Question Game, the more letters are in a question, it becomes more unstable because it can also hide the confetti and balloons when you get a question right, to the point where it can also be like the Jestbook and also end up hiding the background. All settings where in default.
Steps To Reproduce	1. Insert coins. 2. Go to Jestbook or Funny Question Game. 3. Select a category. 4a. You'll see in Jestbook the text it's not completed and also hides the background, if you scroll the text it's glitchy, when all the text dissapears you can see the background again. 4b. The more text it's in Funny Question Game, the more graphics will go missing/flickering.
