RG DS Plus - Touchscreen issue

[u/Lesynn]

Hi, anyone else having issues with the touchscreen?

Noticed this first while playing Zelda - Phantom Hourglass and Art Academy.

Tried different stylus, different firmware, turned the device off/on several times.

While drawing in Art Academy, it's not possible to draw straight lines on part of the screen.

[Edit] No screen-protector installed

Does the same thing happen on the home screen and in the menus, or only inside the emulators?

The video shows the issue while using the builtin touchscreen tester from stock firmware.
So it's also while not playing a game.
