If the scanline shader isn't part of the default shaders list, feel free to ignore this, I did add a few shaders I found here on the forum.

But it looks like the latest update for GLES 3.2 compatibility broke the scanline shader.

Dunno what the problem is, every other shader is working. Any ideas?

Nvidia changed the driver(s) for The GPU. So APIs were changed too. The scanline filter works fine, but if your device doesn't have the data, either being more up to date or out dated, the code can not be rendered. It's because of incompatibility. Your bad ace tablet & the video filter are fine.
