Why did the quality of the GUI deteriorate by half after creating the exe file with jpackage? - libgdx

Question

I'm using jpackage to convert the jar file to an exe, with the exe file provided by the internal JRE. As a result of the conversion, good results were obtained, the JRE weighs about 38.5 mb.
When I run the exe, the GUI quality is twice as WORSE as in a normal jar! In addition, the window of the new exe file increases on its own. Thus, very strange changes appear, as if the exe file is trying to imitate a window jar file. I want to point out that I am using libGdx for the GUI.
