HI, Andrew.
The fix looks fine, but in my opinion we can add this ifdef to jdk8 fix
to skip possible regression, but in jdk9 it is better to avoid this
ifdef for two reasons:
- This will increase a coverage of a new code not only on osx but also
on other platforms and drivers.
- It should
I think that is a reasonable compromise. Miminis 8ux risk but let's get
some exposure in 9 ..
So approved.
Still, very interesting what Andrew notes about D3D being so much faster ..
seems like a subject for further study at some point.

Given that it is a unified driver it sounds like we may be want
to disable this code path when on windows at least for NV but I guess we
may also want to validate that on some other cards - from Nvidia - to

It has been noted that we now have LCD text in some cases

Hello Sergey,
the only part of the fix affects the performance of AA case: the cache
cell size.
In a case of retina, 13pt and 20pt glyphs do not fit the 16x16 cache
cells,
so these benchmarks show better performance:
13pt: 40-80 times faster
20pt: 7-13 times faster
6pt shows the same
Hi, Andrew.
Can you additionally provide the bench data about aa(before/after the
fix) vs new lcd lcd?
Probably it well be more obvious if the code in OGLTextRenderer

1008 dstOps-textureTarget == GL_TEXTURE_2D)
Will be moved

thanks a lot for trying the fix with netbeans. According to the

the fix should provide some improvement on system with modern Intel

Unfortunately, the effect of the fix highly depends on graphics hardware

Hello,

The root of the problem is that we have to supply a content of
destination surface to lcd shader to compose the lcd glyph correctly.
In order to do this, we have to copy a sub-image from destination

This patch dramatically speeds up subpixel font rendering on OSX in
netbeans! It even makes netbeans usable on intel integrated graphics
on retina screens! Excellent work!
It also makes netbeans scrolling butter smooth when not using subpixel
rendering.
