ILSpy running without showing GUI in tiling wm environment

[766F6964]

System:
OS: Arch Linux x64
Kernel: 5.5.8-arch1-1
Window Manager: bspwm

Summary:
Compiling AvaloniaILSpy and running it results in not showing the GUI. No error is thrown.

Steps to reproduce:

1. Install Arch Linux with bspwm as window manager
2. Download the source code of AvaloniaILSpy from GitHub
3. Run the build.sh script to compile the project.
4. Start the generated x64 linux binary, and observe the process running without showing a GUI.

Notes:
I am not entirely sure if this problem is actually occurring because the system is using a tiling window manager.
But since the same procedure works just fine on other linux systems that use e.g. Gnome or KDE, I am assuming it is related to the window manager.

Can confirm similar behavior using i3 with a fresh Arch install, both by downloading and compiling from source, and via the AUR package. Some dependency missing?

I am seeing the same thing on Gentoo x64 with i3. I actually let it sit for over an hour and it eventually prints this and dies:

$ ./ILSpy

Could you try some other applications using Avalonia? https://github.com/AvaloniaUI/Avalonia/wiki/Projects-that-are-using-Avalonia

Interesting, got 2 different results for the 2 applications I managed to get running.

fvim v0.2.348+81a158c exhibits the same problem.
wasabi v1.1.12.2 runs correctly.

Also, digging further...this somehow seems to be font-related...running under strace shows that after initial startup it keeps spamming this system call indefinitely:

access("/usr/share/fonts/liberation-fonts/LiberationSans-Regular.ttf", R_OK) = 0

Possibly looks like it might be this issue? AvaloniaUI/Avalonia#3859

I have Dejavu fonts installed, so it may be the Microsoft fonts that it needs. I'll try that out tomorrow.

[matoro]

Yes, that fixes it. I installed media-fonts/corefonts on Gentoo, ttf-ms-fonts is the corresponding package on Arch. Perhaps that should be noted as a required dependency...

@matoro thanks! Let me note it somewhere.
