Opening Jabref gives no workable display

JabRef 5.0-dev--snapshot--2019-04-03--master--a273eb1fa
Windows 7 6.1 amd64
Java 1.8.0_201

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Since some snapshot versions, starting jabref after starting windows ends with no display at all, all I see is an empty window at the taskbar. The remedy for this is to start an old version of jabref (4.1) and closing it. Thereafter Jabref 5.0dev snapshot starts without any problems.

@Siedlerchr I tested it once and it seems to work. I will check again at the following days whether the error is really gone. You may close the issue until I report back.

Okay thanks for your feedback!

I have this similar problem with JabRef 5.0 (which was working fine last month). If I try to run JabRef it initializes and I get a taskbar icon, but it remains blank in the ALT-TAB preview and if I click it I get nothing.
I tried re-installing, but this hasn't solved the problem.
