[RPi4, GLES] Cannot use HW renderer when PGXP Texture Correction is turned on #64

Closed ectorhga closed 1 year ago

ectorhga commented 1 year ago

Hi, I'm using Swanstation on a Raspberry Pi 4 (Buster, 32bit, 2GB RAM, KMS driver enabled) compiled from the master branch with HW GLES renderer.

I have noticed, that I get an error when I start Swanstation with "PGXP Texture Correction" turned on (see verbose log). The error message that pop up is "Failed to initialize OpenGL renderer, falling back to software renderer". I can start Swanstation in HW renderer mode without the texture correction and enable it afterwards, but I'm not sure, if it works or not.

Here are my Swanstation core options, if that helps.

Could you please check if it still happens with the latest update.

It's fine now, thanks a lot! Just out of curiosity, as I I don't really understand what you changed: is the Texture Correction not working with GLES or was there a different problem?

It had to do with non-perspective colors not being properly supported on GLES.
