examples/basic: Blank screen

[powellnorma]

git clone https://github.com/webview/webview_go
cd webview_go/examples/basic/
go run main.go

System: go version go1.21.4 linux/amd64

The cursor changes when I hover over where the text is supposed to be, but otherwise its just a blank white screen. In a VM (go version go1.21.4 linux/amd64) it works fine. Has anyone an idea what the issue could be?

I tried to use webview.New(true) in hopes of some helpful logs, but only get this:

The helloworld wails app worked fine though: https://wails.io/docs/tutorials/helloworld/

I have updated all system packages, and now it works. But why did the helloworld wails application work fine, while examples/screen didn't?

Btw, I now get these two additional lines:

libEGL warning: DRI2: failed to authenticate
libEGL warning: egl: failed to create dri2 screen

They were missing before. Not sure if that could be relevant

Now it happens again. Since it also happens with the C version, I reported it here: https://github.com/webview/webview/issues/1055
