I write a display mirror driver for capturing screen .
In this driver, I create a share memory and force GDI to output to this
memory with 16bit bitmap format. In user mode application, I read this
memory again to view the bitmap.
But, there is something wrong when the whole system memory utilization
becomes high, the bitmap becomes incorrect partly.
I'm sure it's the driver bug, Not user mode application bug!
Someone help me?!
