Sorry for long delay – I understand the error, but to investigate and reliably fix I need an access to macOS with different screen settings. I’m looking how to organize it, it takes a while 🙂 For what it’s worth, it works correctly for me with my current (and single) monitor OK. But I cannot test with second monitor, or a different monitor – because the macOS I use is a remote machine provided by [https://www.macstadium.com/](https://www.macstadium.com/) . It’s a great way to use mac (and share it with a team, see [old blog post about it](https://castle-engine.io/wp/2022/05/29/huge-improvements-for-macos-users-macos-binary-beta-release-cocoa-backend-for-tcastlewindow-automatic-running-and-packing-using-appbundle-access-to-macos-thanks-to-macstadium/) ), it has served us well… but the limitation is that I don’t really have a physical mac, I cannot swap monitors to which it is connected. Below is a screenshot how it – correctly – looks for me. I will get back to this thread once I managed to reproduce and fix the scaling problem, have patience with me please 🙂 (And if you’d like to help, the hint is that the bug is most likely inside Cocoa + TCastleWindow code, in file [castle-engine/src/window/castlewindow\_cocoa.inc at master · castle-engine/castle-engine · GitHub](https://github.com/castle-engine/castle-engine/blob/master/src/window/castlewindow_cocoa.inc) . We most likely miss scaling there by some per-monitor value.) ![obraz](https://forum.castle-engine.io/uploads/default/original/2X/8/89722a4067f86ce8594067c849cbba4801211b31.jpeg) --- _[View the full topic](https://forum.castle-engine.io/t/mac-os-access-violation/1197)._
