I've already submitted PR #1870 to fix the sizing test failures on Mac and Windows. The problem is not with the tests. When the platform code enforces the min/max restrictions it has to send a notifySize event to ensure the window properties are updated correctly. ------------- PR Comment: https://git.openjdk.org/jfx/pull/1789#issuecomment-3338971001
