@aivanov-jdk Thank you for testing it on Win 10 & 11. I'm unable to replicate this issue on windows 10. But as you mentioned earlier, I was able to see similar icon distortion when using the DisplayChangedListener approach. I'll check what might be causing the issue on Win 11 and if it is replicable on Win 10 for any particular scenario.
