Steps to reproduce:

1. Open a Unity Project on a two or more monitor setup (ensure two monitors are of different resolutions). This bug can occur on a single monitor setup (such as when first opening the windows) but repro is consistent on a multi-monitor setup
2. Move the Unity Editor to one of the monitors
3. Open the About Unity Window at Help > About Unity
4. Close the About Unity Window
5. Move the Unity Editor to a different monitor of another resolution
6. Open the About Unity Window at Help > About Unity
7. Observe the window size
8. Close the About Unity Window
9. Re-open the About Unity Window
10. Observe the window size

Actual results: The first time the About Unity Window is opened when the Unity Editor is on a new resolution (whether that is because the Unity Project has been opened for the first time or has been moved to a new monitor), the window will either open far too big or far too small.

You have to close and re-open the window to get the correct size.

Expected results: The About Unity Window always opens at the correct size
