X11: No display config with transparency
fxdave opened this issue · 11 comments

My setup supports transparency, so I don't understand why glutin doesn't find a config that supports it:
let config_template = glutin::config::ConfigTemplateBuilder::new()
.prefer_hardware_accelerated(None)
.with_depth_size(0)
.with_stencil_size(0)
.compatible_with_native_window(raw_window_handle)
.build();
let config = gl_display
.find_configs(config_template)
.unwrap()
.take_while(|config| !matches!(config.supports_transparency(), None | Some(true)))
.last()
.unwrap();
if let Some(false) = config.supports_transparency() {
println!("This GL config doesn't support transparency.")
}Somehow I always get a config with transparency support of Some(false).
How can I acquire a config with transparency?
fxdave commented
It looks like, despite it is Some(false), it is transparent
kchibisov commented
Could you describe what your setup is?
I'd still like to know why it's Some(false)...
fxdave commented
I'm using BSPWM on an optimus laptop.
However, nvidia is now turned off and I only use Intel iHD driver for Intel(R) Gen Graphics - 23.1.0
I get this from sudo X :2 -configure. I tried to find a way to dump the current config. It seems that's the closest way to dump.

If I start a compositor like compton or picom, I get the same result.

I don't know whether it helps or not but as far as I know, XCB doesn't have this config finder functionality. It just works with transparency: https://github.com/fxdave/simple-clock-rs
kchibisov commented
Were you actually using GLX though in glutin, is glutin example transparent for you?
The thing about transparency with OpenGL on X11 is that it depends on mesa and X11 visuals, so we check if you have alpha mask or not.

I'm surprised that it works in your case.
If you want transparency to GlxThanEgl and please, pass x11_visual to winit, check out glutin-winit on how to do that.
kchibisov commented
EGL on X11 doesn't support transparency in general. It's a mesa bug, not sure how it worked.
fxdave commented
I found that it was more stable with EglThanGlx, not sure why, but that's why I changed it. But it runs fine now.
In case it was a mesa bug it might be fixed then, because it supports transparency just fine. I'm not sure what picom uses though (probably glx).
However, it still gets Some(false). If I explicitly state that I want with_transparency(true), it becomes Some(true).
Isn't this config template only for filtering?
With EglThanGlx and with_transparency(true) it simply crashed on the unwrap, so it's a progress.
fxdave commented
I still had problems with this so I made some tests:
I use this WindowBuilder:
WindowBuilder::new().with_transparent(true)...Testing

It seems Egl is the most stable backend. It supports transparency, but on Intel the gl_config somehow doesn't tell us that.
I ended up using glutin-winit and I wrote a good config selector. Unfortunately, it's still possible on Intel with Egl that the transparency won't work since we cannot guarantee it based on the config.
Here's my config selector:
let (window, gl_config) = glutin_winit::DisplayBuilder::new()
.with_window_builder(Some(window_builder.clone()))
.build(event_loop, template_builder, |configs| {
// Find the config with the maximum number of samples
configs
.reduce(|acc, current| {
let is_current_transparent = current.supports_transparency().unwrap_or(false);
let is_acc_transparent = acc.supports_transparency().unwrap_or(false);
let gain_bigger_samples = current.num_samples() > acc.num_samples();
let case_transparency_is_not_supported =
!is_acc_transparent && !is_current_transparent && gain_bigger_samples;
let case_transparency_is_supported =
is_acc_transparent && is_current_transparent && gain_bigger_samples;
let case_transparency_become_supported =
!is_acc_transparent && is_current_transparent;
let is_current_better = case_transparency_become_supported
|| case_transparency_is_supported
|| case_transparency_is_not_supported;
if is_current_better {
current
} else {
acc
}
})
.unwrap()
