2 weeks ago @xEricL, I can't reproduce
Here is the code I'm using
package main
import (
"bytes"
"embed"
"image"
"image/png"
"github.com/AllenDang/giu"
)
//go:embed assets/*
var assets embed.FS
var (
logo *image.RGBA
window *giu.MasterWindow
)
func main() {
window = giu.NewMasterWindow(
"Updater",
377, 144,
giu.MasterWindowFlagsFrameless|giu.MasterWindowFlagsNotResizable|giu.MasterWindowFlagsTransparent,
)
logo, _ = loadImage(assets, "assets/logo.png")
window.Run(defaultUI)
}
func defaultUI() {
giu.SingleWindow().Layout(
giu.Align(giu.AlignCenter).To(
giu.Dummy(0, scaleDivider(6)),
giu.ImageWithRgba(logo).Size(80, 80),
giu.Dummy(0, scaleDivider(6)),
giu.ProgressBar(ReadProgress()).Size(scaleValueX(377)*0.75, scaleValueY(5)),
),
)
}
func ReadProgress() float32 {
return 0.5
}
func scaleDivider(value float32) float32 {
_, yScale := giu.Context.Backend().ContentScale()
if yScale > 1.0 {
value *= 2
}
return value * yScale
}
func scaleValueY(value int) float32 {
_, yScale := giu.Context.Backend().ContentScale()
return float32(value) * yScale
}
func scaleValueX(value int) float32 {
xScale, _ := giu.Context.Backend().ContentScale()
return float32(value) * xScale
}
func loadImage(assets embed.FS, path string) (*image.RGBA, error) {
data, err := assets.ReadFile(path)
if err != nil {
return nil, err
}
img, err := png.Decode(bytes.NewReader(data))
if err != nil {
return nil, err
}
return giu.ImageToRgba(img), nil
}It works fine (assets/logo.png for me is examples/loadimage/gopher.png)
I've a suggestion for your project: make sure your style.go does not use AllenDang/imgui-go - you need AllenDang/cimgui-go

What happend?
This code worked in v0.7. Updating to v0.8.1 causes a segment violation at runtime.
Code example
```golang //go:embed assets/* var assets embed.FS var ( logo *image.RGBA window *giu.MasterWindow ) func main(){ window = giu.NewMasterWindow( "Updater", 377, 144, giu.MasterWindowFlagsFrameless|giu.MasterWindowFlagsNotResizable|giu.MasterWindowFlagsTransparent, ) logo, _ = loadImage(assets, "assets/logo.png") window.Run(defaultUI) } func defaultUI() { giu.SingleWindow().Layout( giu.Align(giu.AlignCenter).To( giu.Dummy(0, scaleDivider(6)), giu.ImageWithRgba(logo).Size(80, 80), giu.Dummy(0, scaleDivider(6)), giu.ProgressBar(ReadProgress()).Size(scaleValueX(377)*0.75, scaleValueY(5)), ), ) } func scaleDivider(value float32) float32 { _, yScale := giu.Context.Backend().ContentScale() if yScale > 1.0 { value *= 2 } return value * yScale } func scaleValueY(value int) float32 { _, yScale := giu.Context.Backend().ContentScale() return float32(value) * yScale } func scaleValueX(value int) float32 { xScale, _ := giu.Context.Backend().ContentScale() return float32(value) * xScale } func loadImage(assets embed.FS, path string) (*image.RGBA, error) { data, err := assets.ReadFile(path) if err != nil { return nil, err } img, err := png.Decode(bytes.NewReader(data)) if err != nil { return nil, err } return giu.ImageToRgba(img), nil } ```main.goYou can also find the actual code I'm using this for here: https://github.com/alpine-client/pinnacle/blob/084fde184a816b2241c36bd4f37a9fced3f21dbf/ui/ui.go#L83
