Hi All,
Please review the fix for JDK 10. Bug: https://bugs.openjdk.java.net/browse/JDK-8159062 Webrev: http://cr.openjdk.java.net/~psadhukhan/pankaj/JDK-8159062-webrev.00/ Issue: There are issue with the mouse move events when HIDPI scale is set to some non-integer value like 1.25, 1.5, 2.5. Fix: The issue is due to precision error. In native side in the awt_Win32GraphicsDevice class, ScaleUp and ScaleDown functions are used to get scaled value where ceil is used. But in java side, ClipRound is used which rounds the value instead of ceil. I think we should be doing round in native side also. This fixes the issue. Regards, Pankaj Bansal
