Example demo crash in WSL2 environment

[mhauzz]

First time poster here, Hi!

I have been successfully running my little imgui projects in the past, but recently they started crashing in WSL2. Seems to happen with demo examples as well (with a freshly cloned repo). GDB backtrace for example_glfw_opengl3:

WSL2 info:
OS: Ubuntu 22.04.3 LTS on Windows 10 x86_64
Kernel: 5.15.133.1-microsoft-standard-WSL2

I would appreciate any help here!

Apparently this has been fixed e.g. by a WSL update or maybe a "sudo apt upgrade". Note that I have not updated the imgui repo clone on my laptop for a while, so the issue must have been elsewhere to begin with.

Thanks for posting this update.
