Changing Screen Layout does not immediately change

[DarkSide1305]

What version of melonDS DS are you using?

0.7.27

Does the problem happen in standalone melonDS?

I don't know.

What happened?

When you change the Screen Layout (from Top/Bottom to Rotated Left for example), the image is stuck in the resolution of the previous setting. So when you set it from Top/Bottom to Rotated Left, its squeezed into the area of Top/Bottom (
). Only upon a restart does it change to a proper aspect Ratio (
).

What should've happened instead?

The Aspect ratio should change immediately upon changing, for games that require spontaneous change like the Big Bowser Fights in Bowser's Inside Story.

Which platforms do you see the problem on?

• Windows
• macOS
• Linux
• Android
• iOS
• tvOS
• Other (specify below)

Which versions of the OS?

SteamOS 3.5 (or the newest version currently available)

Which libretro frontend are you using?

RetroArch 1.16.0 (newest Flatpak)

Could you post a log of you reproducing the issue?

This is a Log going from "Rotated Left" to "Top/Bottom", where the screen doesnt immediately update to be non-stretched.

I cannot reproduce this issue on my Steam Deck, at least not with my build of RetroArch. I'll try this with the Flatpak release next. I wonder if this is a RetroArch bug that was fixed recently?

[JesseTG]

I cannot reproduce this in the Flatpak build either. Could you try the latest release and see if the issue persists there? That release updated some relevant dependencies, including the one I use for the screen layout's math.

[DarkSide1305]

I will give it a try, I have not tried the newest Release yes as nothing seemed to fix the issue, but maybe somehow its fixed.

[DarkSide1305]

Nope, it has the exact issue. Let me record a video for you so I can show it.

In this video you can see how when I change the Screen Layout, it does not set to the new layout until I give RetroArch a restart. At the end you could also see me click "Close Content" which did nothing (#134), as you can see me cursoring around in the Menu but not in RetroArch.

Ah ha! There we go. I have reproduced this bug successfully. I initially misunderstood the steps you were taking; I thought you were just pressing the "Next Screen Layout" button, which is what I had been doing. You were adjusting the current layout in the core options menu. I expect that most people will change the current layout with the Next Screen Layout button, but changing it directly in the options menu is supposed to work.

Thank you for the video and for the bug report. They were both helpful.
