[BUG} overlay issues

[Veund]

im using the dev build of gb studio on windows 7

when i use the overlay function after a display text, the text box is on top of the overlay at the top of the screen

Intended, It's a feature!
The Gameboy's Overlay layer is used to draw text without breaking the background.
Use Show overlay to clear/make the overlay layer completely white or black.

yeah, i know how they work, I'm saying the display text is getting stuck on the overlay when you run an overlay after a display text as shown on my second photo with the text box at the top of the screen

It would be wasteful to clear the overlay layer after every text box, and the show overlay function (Not Move overlay) already has the option to clear.
Your script of

Hide overlay,
Text "MORTALS!!!",
Wait 0.5 sec

Does not produce the shown result.

I may have missed a show overlay

Add a show overlay after the wait

[RichardULZ]

For anyone else that encounters this.
Show Overlay and Move Overlay are different functions, Show Overlay will fill the buffer White or Black, with a position, set that to X0 Y18 to clear it while off screen,
Move overlay will only move it, not clear.
This is Important for later features / text box functionality, and working as intended,

TL;DR solution.
Use Show Overlay (Black) (offscreen) before Move Overlay after using a text box.
