import (
g "github.com/AllenDang/giu"
)

func loop() {
g.SingleWindow().Layout(
g.Style().To(
g.Label("test"),
),
)
}
func main() {
g.Context.FontAtlas.SetDefaultFontSize(12)
wnd := g.NewMasterWindow("test", 1024, 768, g.MasterWindowFlagsMaximized)

While the help message say to do so.

// SetDefaultFontSize sets the default font size. Invoke this before MasterWindow.NewMasterWindow(..).

You're right - something is borken inside font atlas right now... SetDefaultFontSize doesn't work anyhow 😄

ok, I see - context is nil because it is created in NewMasterWindow. THe problem is that init font stuff happens there as well. Need to add extra logic in SetDefaultFontSize.
