egui: Can't run any of the examples in Windows, error "swap contol extrensions are not supported"

I tried to build few examples on Windows and was getting the error:

error: `-Csplit-debuginfo=unpacked` is unstable on this platform

Once I commented the line split-debuginfo = "unpacked" in root’s Cargo.toml, now I’m getting:

C:\git\egui\examples\hello_world>cargo run
warning: C:\git\egui\crates\eframe\Cargo.toml: unused manifest key: target.cfg(not(target_arch = "wasm32")).dependencies.glutin.es
   Compiling hello_world v0.1.0 (C:\git\egui\examples\hello_world)
    Finished dev [unoptimized + debuginfo] target(s) in 1.84s
     Running `C:\git\egui\target\debug\hello_world.exe`

error: process didn't exit successfully: `C:\git\egui\target\debug\hello_world.exe` (exit code: 1)

If I run release version the .exe file just exits

C:\git\egui\examples\hello_world>cargo run --release
warning: C:\git\egui\crates\eframe\Cargo.toml: unused manifest key: target.cfg(not(target_arch = "wasm32")).dependencies.glutin.es

rustc version is fixed in rust-toolchain to 1.65.0-x86_64-pc-windows-msvc, however I tried to remove it and use 1.66.0 as well as nightly with the same result, I also tried on current master branch as well as 0.20.1 without luck. On 0.20.1 however I was able to capture call stack:

This is not a glutin error. virtual box windows only provides opengl 1.1 and that is not enough for egui renderer. So, the crash is explicitly caused by egui_glow.

[2023-06-06T20:20:11Z DEBUG egui_glow::painter] opengl version: 1.1.0 opengl renderer: GDI Generic opengl vendor: Microsoft Corporation thread ‘main’ panicked at 'some OpenGL error occurred egui_glow requires opengl 2.0+.

Your best option is to go with software rendering https://github.com/emilk/egui/issues/1129

or wgpu if that works.

there’s Egl with opengl es 3.0 (using angle)

ANGLE isn’t supported by glutin and never was, patches are welcome though(https://github.com/rust-windowing/glutin/issues/1508).

@kchibisov is it possible to factor in both Egl and Wgl features during display creation? as you can see in the above comment’s wglinfo.txt, there’s Egl with opengl es 3.0 (using angle) with all sorts of extensions, but glutin-winit will still choose Wgl which doesn’t have any display features/extensions at all (swap control or robustness etc…).

You’d need to create both displays and ask for features each of it. I think you can do such a thing and then drop the displays, but you’d need to add library unloading into glutin to conserve resources.
