Error running examples

[VarLad]

Hey, I've been trying to run the example uiExample.jl from the master branch
I see the window but then it crashes with:

[ Info: Setting Log level : WGPULogLevel_Debug
INFO Instance version: 0x403105
INFO Enabling device properties2
DEBUG Client extensions: []
INFO EGL_MESA_platform_surfaceless not available. Using default platform

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
fatal runtime error: failed to initiate panic, error 5

Any idea whats going on?

@VarLad Are you on Linux machine ? Linux machine has issues with GLFW library. It works on Mac and Windows. Thats something I couldn't narrow it down. I will raise issue with minimum code. It should give you an insight.

[arhik]

Raised issue here with minimal code example #12. FYI.

[arhik]

@VarLad Can you verify by trying minimal code I shared in #12.

@arhik uiExample.jl is giving a different error now:

Can you give me a minimal simpler working example to try?
By the way, I'm using the main branch of WGPUgfx.jl WGPUNative and WGPUCore if that makes any difference.

[arhik]

At line https://github.com/JuliaWGPU/WGPUCore.jl/blob/main/src/linuxglfw.jl#L83C43-L83C43 replace instance with instance[].

[arhik]

linuxglfw.jl needs changes with API changes. But will be minimal. uiExample.jl is incomplete, but you can still use it. It's all display code that needs to be fixed. If I could fix linux issue I will push it myself. But it could good first PR for you to get started.

[arhik]

The code in the following commit worked for me. JuliaWGPU/WGPUCore.jl@734f402

Run recently edited examples. Other examples need to be updated.

[arhik]

This should work now. I tested it on a Linux x86_64 hardware.

@VarLad Let me know if this can be closed once checking on your system.
