The same problem happens to me using the Windows .jar (1.0) version AND maximize-ing the window.
With default window size it works.
I'm using it with Win7-Pro-64 and javaw.exe "Java(TM) Platform SE binary" (in [...]\Java\jdk1.8.0_172\bin\javaw.exe ; using «java.exe -version» it tells «Java(TM) SE Runtime Environment (build 1.8.0_172-b11)») wich is "Java 8 update 172" (and "Java 8u172", see: oracle.com/technetwork/java/javase/jdk8-naming-2157130.html) it should be from 20180417 (java.com/it/download/faq/release_dates.xml).
[I know it's all old... I'm upgrading PC and OS now]
