OpenGL renderer bug

[HFPasfho]

• Device model: S9
• Android version: 10

Problem:
White borders around blocks and handles (red and blue diamond-shaped things) are not visible when using OpenGL renderer in Picross 3D.
It's a bummer, because this game benefit greatly from a higher rendering resolution.
Additionally, when using OpenGL, the image appears slightly less sharp than when rendering in software mode (I use nearest neighbor scaling in software mode).

Screens at x1 resolution scale for easier comparison:
