: 1. It happens to be sometimes (1 in 20-30 times) that whenever i try to
: wtite a text to lcd display or fill a bar the text is written horizontaly
: about some percentage (say 50 %) and then again writes the same text the
: remaining percentage makeing the display as if one text is written twice
: half and half one over the other .
:
: Similarly when we are dispalying the a horizontal bar the bar gers
: displayed two times one over the other horizontaly.
I'm still confused as to whether you're describing a hardware
jitter or suggesting that perhaps the software is drawing
multiple times to appear "jittery." I don't think there
are any known bugs regarding the latter. I assume
you are running a straight framebuffer driver. If not,
then there are additional drawing issues.
: Is there any thing we could see into the microwindow ???

: Please do share your experience and knowledge regarding this concern .
Carlo's response regarding the OS framebuffer driver sounds
like something that can definitely be related to visual strangeness.
Notice this also applies to a system where there isn't really
a memory-mapped framebuffer, but some other mechanism
for drawing.
