I believe this problem may also be reproduced on win95 and other
jdk1.2 versions.

To reproduce the problem, do the following:
1) Set the display colour depth to 8 bits per pixel (256 colours)
2) Set the desktop colour to something other than the 'Windows
Standard'. This is done under the 'Appearance' tab of the
'Display Properties' panel.
(Note that only some colour schems cause this behaviour,
'Rainy Day' is an example).
3) Run any swing application, instead of appearing solid, the
colours are stipple in appearance.
4) When I simulataneously run a jdk1.1 application I do not see
this effect.

Although I have not been able to investigate this problem any
further, it seems likely that it is a palette management issue.
However, when in the foreground the application should be able
to lock down enough palette entries to achieve a non-stippled
appearance. It is worth noting that the effect is also seen when
using the Swing Windows look and feel, in this case their should
not be any such issues, since the same palette entries will be
locked by Windows itself.

As a final note, particularly unpleasent effects may be achieved
by changing the desktop colour scheme while a Swing application
is running.

java version "1.2.2"
Classic VM (build JDK-1.2.2-W, native threads, symcjit)

When running a Swing (JDK 1.2.2) applet with the Java Plug-in 1.2.2 that
contains 256-color .GIF images, on an MS Windows 98 display that is in 256-
color mode, the colors appear in technicolor (reverse graphics, x-ray graphics,
inverse graphics, whatever you want to call it). It appears that the
background palette is being realized instead of the foreground palette and so
the wrong colors are mapped to the images when displaying them. This only
occurs on some displays that are in 256-color mode, and only on MS WIndows 98.
Increasing the color mode to 16-bit color or higher eliminates the problem.
This is not however a workaround for all customers, since some of them cannot
change their displays to a higher color mode.
