Hi.
I’m developing Mirror Display Driver.
And I got one strange situation.
I’ve been testing my driver on different computers and found that on one of 3 computers my driver isn’t working correctly.
I see that when I move mouse cursor fast some areas on driver’s surface is drawing not correctly (I’m sure that this problem isn’t in ring3 app).
It looks like some lines of pixels are rendered in a wrong place.
Here on this screenshoot you can see what I’m talking about http://img68.imageshack.us/img68/3743/wrongplacebn7.png
I have ATI Radeon 9500 Video card on this computer.
Strange that on VMware Workstation (Virtual Machine) I don’t see there artifacts and on notebook for example I don’t see this too.
Could someone can say something about this situation, I don’t what way to look and it strange for that this happens not on all computer (but with Radmin for example it’s doesn’t happens)
Your link doesn’t work (the image is not present), at least for me.
I don’t know much about video, but just as a comment, I would note that
your three targets potentially have different video support. The one
with a problem is PCI/PCI-e/AGP, the notebook is something embedded, and
the VWWare is an emulated something or other (S3???).

Is working on my computer, maybe you coped not correctly.
Maybe there is a problem in different displays, but I had another normal computer and on that computer my driver worked correctly and if my driver isn’t working correctly then why radmin’s driver is working normal.
I think there is something I did wrong or I need to add something in the code.
I’m getting some sort of script error when I try to display this page
(in Internet Explorer). Maybe I don’t have a filter for png support.
As I’m not likely to have much useful to say about the particular
problem you are having, it doesn’t really matter, assuming that others
(say, I don’t know, Tim) can display the page correctly.
