egui: BadMatch error in hello world example on X11

Hi,

I was trying to run the hello world example on master @ d01e4342, but it crashes with the following error:

$ RUST_LOG="debug" cargo run -p hello_world

Note that this is not a panic, but an error that is handled. I’m not sure where exactly it’s coming from.

If I checkout 0.20.1, I get the same error but with a panic, with the following backtrace:

I did a git bisect and found that the crash starts occurring at https://github.com/emilk/egui/commit/8eb687cf04dd2b68dfe467d142db6b8759425e16, before that it works.

I’m on Ubuntu 20.04.5 with X11 on an ancient Thinkpad. If I run the basic window example from glutin 0.30.0 (which works), it prints

Running on: GLX 1.4
Picked a config with 0 samples
Running on Mesa DRI Intel(R) HD Graphics (ILK)
OpenGL Version OpenGL ES 2.0 Mesa 21.2.6
Shaders version on OpenGL ES GLSL ES 1.0.16

I tried to run the hello-world example of glow, but I get some other error. I also tried to see if #2526 would fix this, but I get a different error there.

Here is the output of glxinfo:

I’m a total noob wrt graphics, so I don’t really know what’s going on. Is there something I can do to investigate this further?

The glutin 0.30.5 is out, so this could be closed.

Using that patch, it works! Now the error is caught like in 0.30.3, and it prints ... due to error: [a7] GLXBadFBConfig.

Thanks a million.

Just so you won’t waste your time, I’ll post a patch shortly handling your issues.

kchibisov on Feb 11, 2023

this is the code for context creation

glutin code

a check is made for latest x11 error at line 53
if there’s no error and the context is still null at line 56, we get a BadContext error (“argument does not name a valid context”)

in 30.4 xtrace log, after trying to create context, winit’s x11 error callback is called and it logs this

2023-02-10T08:03:27.788826Z ERROR winit::platform_impl::platform: X11 error: XError { // this is not detected by glutin 30.4's error checking.
    description: "GLXBadFBConfig",
    error_code: 167,
    request_code: 152,
    minor_code: 0,
}    
// but glutin didn't receive the BadFbConfig err at line 53 -> it continued to BadContext err msg instead at line 57
2023-02-10T08:12:52.373429Z  WARN eframe::native::run::glow_integration: failed ... due to error: argument does not name a valid context

in 30.3, winit’s x11 callback is not triggered at all. so, glutin detects the error properly from queue

// no x11 callback triggered after trying to create context. and line 53 actually catches the error
2023-02-10T08:12:52.373429Z  WARN eframe::native::run::glow_integration: failed  .. due to error: [a7] GLXBadFBConfig
// and never reaches line 56 check. so, no BadContext error msg

In both cases, fallback context creation succeeds. all is good. but inside eframe, we now need to create a surface for the window

before creating surface, we call window.inner_size() to prepare surface attributes. In glutin 30.3 everything is fine. But in 30.4, GLXBadFBConfig (logged by winit x11 callback) stays inside the msg queue of winit and this is caught inside the window.inner_size() fn.

the problem is inside that last_glx_error function and how we are setting winit x11 error callbacks. atleast this log confirms that error is received on time, but for some reason, it is detected by winit and not glutin.

Sorry, I should have read your description more carefully 🤦
