Video Scaling Core provided on philips Google tv shows dark edges/stripes on screen

Description

I installed latest 1.17.0 version of regular and 32 bit android version on my Philips Android TV.

When video Scaling is set to "core provided" it shows two darker edges/stripes with opacity om screen. When I scroll through the menu, the stripes are always there. It looks like an overlay. Background is not full shown.

When I choose "full screen" the dark stripes are gone.

Expected behavior

I would like to no show these dark stripes and change these settings within Retroarch when video Scaling is set to "core provided".

Actual behavior

Current video Scaling settings "core provided" (or any other choice apart from full screen) create 2 dark edges/stripes (with opacity) on both sides of the background. Dynamic Wallpaper is not fully shown and menu looks off.

I tried 4 different file explorer apps and they all can't access secured android folders on my tv. Therefore I cannot access retroarch.cfg to change it manually. I tried loading a manual retroarch.cfg with the changed settings but there is no effect. Ftp access has no effect.

Steps to reproduce the bug

There are no steps needed. It's there from the start when video Scaling has been set to other than full screen.

• RetroArch: [version/commit]
  Version 1.17.0 Android regular and 32 bit

Environment information

• OS: Android on Philips Google tv. TV is from 2022.

No source file or test is named in the report. First reproduce the dark side stripes on a Philips Google TV with video Scaling set to “core provided” or another non-full-screen option, then compare the result with “full screen.” Done means the unwanted stripes are absent while the background and menu display fully.
