Godot version

4.0beta17

System information

MacOS Ventura 13.2

Issue description

When my app enters fullscreen mode, the top of the screen that is not included in the render flickers on and off. I attached a video of this effect. This is very distracting to people trying to play my game.

@RandomWalrus13 Please upload a minimal reproduction project to make this easier to troubleshoot.

Can you reproduce this after switching to the Compatibility rendering method in the top-right corner of the editor?

I have seen a similar issue using the gl_compatibility renderer on PopOS 22.04 with the stretch mode set to Viewport. It seems like the engine is giving the renderer the dimensions minus the title bar even though it expects the entire window to be rendered

Is there a solution to this issue?

Can you reproduce this when using Forward+ or Mobile instead?

This problem does not occur while using the Forward+ rendering method. Although, as far as I know, I do not think you can export to WebGL using Forward+.

No, you can't export to Web with the Forward+ or Mobile backends. Is this issue only reproducible on web export for you?

Yes. This issue does not appear in Foward+ plus rendering. I am using that for now while waiting for the problem to be resolved.
