[Java] jEdit (or other Java application) freezes goes black when dragging it from main monitor to another on multi monitor extended desktop Windows 7 environment

Funny enough, it used to work but after a distributed software update at the office, I have mentioned problem. The freeze was under Windows 7 and 32 bit Java 1.8.0_131. Under Windows 10 and 32 bit Java 1.8.0_131 and HoSpot build 25.131-b11 the java applicatioin does not freeze but on the extended screens black out but the application still works.

The problem is the usage of the Direct3D pipeline. You need to switch it off. Therefore define the environment variable

J2D_D3D

with the value

false

and your done. You just have to restart affected applications (obviously for the freeze anyway).


I found the workaround described at OTN.
