How to prevent OpenJDK 11 from changing the Window size due to some internal reason

[Aleksei Ivanov]

Hi Martin,

I'm afraid there's nothing I can add to the previous discussion in June 
2023 [1].

I can only repeat Phil's statement [2], “Wayland is not a supported 
platform for ANY version of JDK.”


As Kevin suggested [3], you can try builds of the Wakefield project [4] 
or discuss it on Wakefield mailing list, you can even contribute a fix.


At this time, “Wayland is not a supported platform for ANY version of JDK.”
