The fix for https://bugs.openjdk.java.net/browse/JDK-8137571 where HiDPI support on Linux was implemented missed the change in the X11 pipeline, only XRender pipeline was updated. The same logic should be implemented in X11SurfaceData:

 - The size of the native surface should be scaled based on scale factor, except the TEXTURE type, because it is used for managed(cached) images.

See the old change:

I hit this bug on my local system, and confirm that this change cures it. mach5 is green.
