Scaling broke on Wayland (between version `0.24.1` and `0.25.0`): the window is twice the size it should be when the scaling factor is `2`

When the scaling factor is `2` and I set the window size using `ViewportBuilder::with_inner_size()` in EGUI, the window ends up twice the size it should be (4 times the original amount of pixels). Things like images inside the window get scaled correctly

As far as I can tell the bug was introduced between these versions: https://github.com/emilk/egui/compare/0.24.1...0.25.0


(the image and window should have the same size here)

This could also be an [`winit` bug](https://github.com/rust-windowing/winit/issues/3868), I don't know

Reproduce the issue on Wayland with a scaling factor of 2 and ViewportBuilder::with_inner_size(), comparing egui versions 0.24.1 and 0.25.0. Inspect the changes in that range and compare them with the linked winit issue; done means the window and its image have the same expected size at the affected scale.
