Scale breaks when moving egui to a monitor with different dpi #5246

Describe the bug I have a monitor with a scale of 1.0 and one with 2.0. When moving a egui window (e.g. https://egui.rs) from the 1.0 screen to the 2.0 screen egui will be shown with twice the scale it should have. If you then reload it will be shown at the correct scale. Moving egui from the 2.0 screen to the 1.0 screen will cause egui to be shown at half of the expected scale. The mouse events don't seem to be scaled and don't match the visual output.

Note : Seems to work fine on Windows10 + Chrome + (Monitor 1.25 & 2.0) ( Could it be depends on the OS? )
