Hi,
yesterday I installed debian lenny from RC1 installer CDs from scratch. After
fiddeling with the system a bit, I wanted to have this nice fancy splashimage
feature from grub.
So I added a splashimage line to menu.lst (shown below).
In the boot menu it was displayed with stripe patterns on the 640x480 image.
With a closer look you see that there are dashes (8x1 pixels) displayed in
wrong colors. These wrong dahes appear mostly in line 1, 16, 31, 46, ...
(that means 1+n*15). Some of these lines conincide with the horizontal
borders of grub's cursor bar.
The resulting stripe pattern remains always the same (even after several after
reboots), but changes when a pixels is touched by grub's cursor bar.
There seems to be some kind of color shift happening to the wrong displayed
dashes. The wrong displayed color is one of the 14 colors of the XPM image
(or the foreground color or the background color as it is set in menu.lst).
Mostly it's the next brighter color, but not always.
This color shifting can to some degree corrected by manual tweaking the colors
of the xpm image with gimp.
This is of course not the way to proceed for the whole image.
I can attach a photograph of the boot screen if it helps to triage the bug.
Or do I have to blame the graphic card vendor only?
The problem occured also with different monitors (4:3 and 16:9 aspect ratios).
Using xpm images from grub-splashimages didn't change anything.
Thanks for your time and Happy Holidays,
Thomas Braun
