Public bug reported:
Gedit switches to gray-scale font anti-aliasing when the text displayed does
not fit within the window.
To reproduce the bug:
(1) Select the following font settings:
Default font: Liberation Sans, 10
Document font: Liberation Sans, 10
Monospace font: Liberation Mono, 9
Window title font: Liberation Sans Bold, 10
Antialiasing: RGBA
Hinting: Medium
Text scaling factor: 1.00
(2) Open gedit. (Optionally, make the window a little smaller so you
don't have to type so much in the next step).
(3) Type some text and notice that the font selections you made are
being used. (Take a screen-shot for reference).
(4) Continue typing more text, until the text no longer fits in the
gedit window's text area. The vertical overlay scroll bar will appear
at the right window edge (if you have text wrap enabled).
(5) Now that the text you typed does not fit within the gedit window,
notice that the text is no longer as smooth as before. (Take a screen-
shot for reference).
(6) Open and zoom into the screen shot from step 3, and then open and
zoom into the screen shot from step 5. Notice that the colored font
hinting (or anti-aliased font edges) that appearED in the screen-shot
from step 3 are no longer present in the screen-shot from step 5. The
fonts in the screen-shot from step 5 have gray antialiasing / hinting.
I have attached a screen-shots depicting this situation. The left side
of the screen shot shows gedit with good font antialiasing / hinting
(from step 3). The left side of the screen shot shows gedit with bad
font antialiasing / hinting (from step 5). I have also zoomed into the
letter "A" in each respective scenario, and pasted that into the image
to show how the font hinting / anti-aliasing changes when text does not
fit into the gedit window.
