All dialogs displayed by the launcher are scaled too big when using a 4K monitor that scales the window content.

My main display is a 4K monitor with a scale of 200%, the other two are full HD with a scale of 100%.

When loading mods with dependencies on my main display I can't interact with the window. The buttons are out of screen and the dialog can't be scaled.

The only hack to interact with the dialog is to move it to another screen like this:
