ImGui multiple screens & different dpi Issues

Hi all,

since a while i’m experiencing problems with multi screen setup and different dpi settings using ImGui.

This is how ImGui looks on my main screen, 4k DPI scaled to 150%

And this is how it looks on my full hd screen, whitout scalling

As you can see the ImGui content is cropped.

Easy to reproduce, just open any ImGui example.

Thanks

Also random silent crashes moving the skia window along the screens.
