I have a nice handheld (rg280m) running retroarch.
Unfortunately I damaged its screen and it now has a significant and annoying light bleed on its right side.
I considered editing the “darken” filter so to actually enable it on the bled pixels so to even the brightness out.
I could not find a guide about how to do that though, and admittedly I couldn’t still find the difference between shaders and filters so I could admittedly be too clueless to hope to achieve that lol.
Any pointers would be really helpful.
