Issue with .glslp shaders that feature glow/halation/bloom

RetroArch Android devices
#1

I’ve had an issue on my smartphone, that I thought was exclusive to it, but now I have a tablet, also Android, with the same issue. When I have GL as the graphics driver, the shaders work fine… except any of the ones with a glow/halation/bloom effect, which give me a black screen, despite the ROM still running, it just gives me no graphics for some reason, it’s a shame since I happen to love this effect despite knowing it’s not for everyone… strangely, they work when I use .slang shaders on the Vulkan driver, but that seems to run worse on weaker hardware, which is what I have, I wish I could get .glslp shaders with the effects I like to give me something other than a black screen.

Any ideas of what’s going on and/or any possible fixes?

hmm, dunno. If you could get us a log of it showing a black screen, it might tell us what’s up, though.

I see, how do I generate a log that tells me what causes the black screen? I’ve never generated logs on RetroArch, or on Android as a whole, before.

Well, here’s the log I got from playing around with crt-easymode and then switching to crt-easymode-halation, the 1st worked and the 2nd gives me a black screen. I’m not sure if I just don’t know how to read this right, but I don’t see what’s causing the issue in the log…

hmm, yeah, i don’t see anything obvious in there :confused:

I see… it’s a shame, though Vulkan .slang shaders with this effect are working fine up until SNES and Genesis, it’s PS1 and anything more powerful than it that are giving trouble, I guess I’ll just play those system without shaders, or with lighter shaders without the effects I’m into, it sucks, but I guess it serves as motivation for me to move onto better hardware at some point when I’m more financially stable. Once again thanks for helping me out @hunterk! Have a good day.
