And if -Dsun.java2d.uiScale is set to "2" it will use the normal Blit.
It looks like the ScaledBlit uses "direct" access to the gdi surface.
ScaledBlit reads content of the GDIWindowSurfaceData in the GDIWinSD_GetRasInfo
and write it back in the
GDIWinSD_Unlock via BitBlt. Not sure this code mig
You can see the difference here from turning on tracing :-

Yes the test passes with the fix and also passes without the fix if I
don't force uiScale=1.

Blitting a full screen window for me (slightly under 1920x1080) is a
little under 3 ms.
With no need to copy / retry it is a just around 1 ms which I am not
sure whether to trust completely.
On another machine with a finer grained timer it was > 1 ms.

Or, maybe we hit a different code path. I'll check that.
uiScale=1 is the way to ensure we hit this code path.

So you both mean a JDK 15 promoted build without this fix and without

a hidpi setup. And to see the failure without t

@Phil : I think its better if we test at uiScale=1(larger memory footprint).
Please clarify.

Do you have a Hi-DPI machine? I do, and had to run with
"-Dsun.java2d.uiScale=1" in order to see the failure with
LargeWindowPaintTest.
For AlphaPrintTest, the test deliberately ensures that you print before
saying whether it passes or not. FWIW, I verified that the printing test

Hi Phil,
I tried tested the fix in my Windows 10 machine with Intel integrated UHD
Graphics 620.
LargeWindowPaintTest.java passes with/without fix in my machine.
AlphaPrintTest.java without fix just opens up blank frame without any
instructions and with fix it shows instructions for the test.
