I have also recently experienced a similar issue when running egui applications on an Ubuntu VirtualBox VM (tested both 18.04 and 22.04). For me, the GUI is visible but incredibly dark, as if the whole screen was tinted. This does not happen to any other applications that I can tell.

If the issue is openGL driver, software impl might be relevant https://fdossena.com/?p=mesa/index.frag

This has gotten worse with the update to wgpu 0.17. Running cargo run --bin egui_demo_app --no-default-features --features wgpu results in

The wgpu 0.18 update seems to "fix" this again and I'm seeing the empty window described in this issue.

The culprit seems to be the 3D support. The demo works in the VM without the Custom3d demo. Not sure if supporting 3D is possible.
