Description

Adding hyprland shader options!

Use Case

• Greatly help for accessibility by having a pre-configured template, users can copy this file and adjust up to 4 types of visions: // 0:Normal vision, 1:Protanopia, 2:Deuteranopia, 3:Tritanopia
• Then they can adjust the intensity in appropriation.
• Now, why do normal vision care at all? Mode 0 has an option for -1.0 - +1.0 adjustments. Where -1 leans to grayscale and +1 for saturation, which should greatly help productivity!
• Also I want to have paper texture hehe.

Preview

color-vision // Protanopia

Grayscale!

normal vision with 0.4 saturation

the classic invert

Paper

Usage:

All shaders from HyDE are capable to be overridden by making a separate file with the same name and use .inc as suffix instead of .frag

Here's a snippet on one of the shader files.

/*
To override this parameters create a file named './grayscale.inc'
We only need to match the file name and use 'inc' to incdicate that
this is an "include" file
Example:

┌────────────────────────────────────────────────────────────────────────────┐
  │ // file: ./grayscale.inc                                                   │
  │ // integer: 0:PAL, 1:HDTV, 2:HDR                                           │
  │ #define GRAYSCALE_LUMINOSITY_PAL 0                                         │
  │ // integer: 0:HDTV, 1:HDR, 2:HDR                                           │
  │ #define GRAYSCALE_LUMINOSITY_HDR 2                                         │
  │ // integer: 0:HDTV, 1:HDR, 2:HDR                                           │
  │ #define GRAYSCALE_LUMINOSITY_HDT 1                                         │
  │ // integer: 0:No effect, 1:Lightness, 2:Average                            │
  │ #define GRAYSCALE_LIGHTNESS 1                                              │
  │ // integer: 0:No effect, 1:Lightness, 2:Average                            │

CLI

shaders.sh --select - opens a rofi selector to choose shader. It will compile the file.inc then file.frag for HyDE to use.

Basically cat file.inc file.frag > .compiled.cache.glsl

Pull Request Overview

This PR introduces Hyprland shader options to improve accessibility and visual effects by providing a set of pre-configured, overridable shader templates. Key changes include adding a new shader selection/compilation script, updating the Hyprland configuration to integrate shader functionality, and providing multiple shader files (e.g. wallbash, vibrance, paper, oled, color-vision, etc.) to deliver various visual effects.

Pull Request Overview

Adds support for configurable Hyprland shaders by introducing a selection script, shader templates, and wiring them into the main configuration.

• Introduces $SCREEN_SHADER_COMPILED, includes shaders.conf, and sets decoration:screen_shader in hyprland.conf
• Adds shaders.sh to pick, concatenate, and cache .frag/.inc shader files
• Supplies a variety of new shader .frag and .inc templates plus cache and ignore files

Configs/.config/hypr/shaders/grayscale.frag:36

• Macro GRAYSCALE_LUMINOSITY_HDT likely intended as GRAYSCALE_LUMINOSITY_HDTV to match the HDTV standard and avoid confusion.

#ifndef GRAYSCALE_LUMINOSITY_HDT

Configs/.config/hypr/shaders/custom.frag:87

• Missing space and leading zero before the value; it should read #define SHADER_VIBRANCE_SKIN_TONE_PROTECTION 0.75 for clarity and consistency.

#define SHADER_VIBRANCE_SKIN_TONE_PROTECTION.75// Balance: 0.0 to 1.0

Configs/.config/hypr/shaders/custom.frag:71

• Using true in a preprocessor macro may not expand as a numeric value for #if COLOR_VISION_ENABLED==1; replace with 1 or 0.

#define COLOR_VISION_ENABLED true// Set to 1 to enable color vision deficiency simulation

After Lessons i will try out

[UnaTried]

I'll also try this in about 5-7 hours.

[amit-0i]

can you update the waybar_rework branch aswell? (hehe thank you)

Edit:- nevermind, i now realized shaders is a different branch

[Prof-Shiba]

i'll try it in a bit

that paper texture kinda goes hard ngl

[amit-0i]

i have found an issue, when using invert-colors shader the screen starts flickering. i highly doubt its an nvidia driver issue, but i'll like to know about the experience of other testers.

im not visually impaired or color blind, so i cant personally speak to how effective the color-vision filter is but the filters like blue-light-filter, greyscale, paper and vibrance are working great.

great work khing!

(below is the screenshot of the flickering)

[kRHYME7]

Does the flickering happen too frequently? Or it only occur during shader changes?

[amit-0i]

it happens mostly when there is no apps on the workspace and when switching wallpapers. but some minor flickers in applications too

Edit:- looks like closing apps triggering the flickers

[Prof-Shiba]

Invert colors also bugs out for me. Same thing with flickering everywhere.

Also, with the color vision option, it looks visually like it's the same as disabled. It seems a bit redundant, unless I'm missing something.

[kRHYME7]

like it's the same as disabled. It seems a bit redundant, unless I'm missing something.

It is a normal vision by default. The file has instructions on how to use it.

As for the invert , if it flickers seriously I will just remove it for now.

[kRHYME7]

for flickering try to add

debug:damage_tracking = 0

in your userprefs.conf

though this consumes some GPU juice.

[Prof-Shiba]

that made it significantly better. It's still not perfect (a little bit of flashing when closing windows and moving stuff around) but its like 90% better and fairly usable, at least for me.

250524_17h09m13s_recording.mp4

after adding the above, the flickering is limited to only closing windows.

[kRHYME7]

What happens if you disable blur. Maybe it's hyprland?

[amit-0i]

What happens if you disable blur. Maybe it's hyprland?

when blur is disabled, instead of the closing window's trails, the whole screen flashes

[kRHYME7]

Haha hmm 🤔 I'm not capable of fixing this as of the moment. Should I just remove the feature for now?

[amit-0i]

nah its not that big of a deal tbh. we should wait for amd users if they are facing the same issue.

[kRHYME7]

we should wait for amd users if they are facing the same issue.

Will merge this to dev now. We can simply nuke broken frag or add warning in case. So far the reports are hyprland related, so we can't really fix it.

---

If you read the invert-colors.frag it's very simple so I don't know if we can solve it via shader file or hyprland's pre-processor.

Also, I noticed the so-called flicker is from hyprland's effects. It looks like shaders are not being applied for a split second.
