JDK-8069348 - SunGraphics2D.copyArea() does not properly work for scaled graphics in D3D
Description
(just saving here the comment from JDK-8149371)

Sorry, that's most probably the duplicate for JDK-8069348, but it is reproducible with disabled d3d option (-Dsun.java2d.d3d=false) as well as JDK-8148484, so filing it separately (just in case)

Win 7 + JDK9b101

Please run MultiResolutionIconTest.java from JDK-8149371 with options
-Dsun.java2d.d3d=false -Dsun.java2d.uiScale=2
and move one of the windows over the other. Line artifacts will occur (please see the screenshot attached); the same for sun.java2d.d3d=true.

Cannot see artifacts for -Dsun.java2d.opengl=true
Comments
. Kindly refer to my comments above that contains details on- . OS and JDK 9 and 10 builds where the issue was tested . Since the issue was not reproducible, I 'm closing the issue. . If the issue persists, kindly re-open and mention the build that fails.

Quick Observations . I tried reproducing this issue on . Win7 x64 (intel) with JDK 9 (GA) and latest JDK10 builds. . Providing these VM args: -Dsun.java2d.d3d=false -Dsun.java2d.uiScale=2 . I could not reproduce this issue. . Earlier I had tried to reproduce with d3d enabled but realized that the issue pertains to the software pipeline with d3d disabled. Hence corrected this comment.

yes, the issue is still reproducible with JDK9 b125 on my Win. 7 machine (just in case - it has 2-displays configuration, not sure if that may influence). cannot reproduce on Windows 10

I run the test with options -Dsun.java2d.d3d=false -Dsun.java2d.uiScale=2 on Windows 7 and not able to reproduce the issue. Could you check the test with the latest JDK 9 build?
