Re: Display Rendering Problem

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hai Paul,

The below said problem is not only in my code but also in the windows
CE resident codes, that is the applications like
1. Network Configuration in Control panel : When we choose the option
between DHCP and static IP, the UI response delay can be visualized at
one time and at other time it works fast.

2. System Properties in Control panel : When we traverse between
different tabs in the system properties, the same problem occurs.

Yours,
Arun.

Almost anything 'can' be true, yes. You have no indication of slow
operations when the display response is slow at all? That seems very
strange. Check for any Kernel IOCTL handlers that might be taking a long
time or any real-time priority threads in your own code.

Hai Paul,

I have built the OS with Debug option, but I cannot get any clue of my
problem.
Because, it seems that none of the thread is pulling the processor
resource.

Also, at some times, when the OS is up, initially the response is
faster and after sometime, it results in slow response (which is the
inverse of the below problem).

I suspect it may be the display driver problem related to the memory
handling or so.
Can it be true. Awaiting for the feedback.

Yours,
Arun.

Hai Paul,

Thanks for your kind concern.

Also, initially it is Slow, then after some time it is fast and again
it drops to slow UI response that surprises me.

Anyway let me check with your suggestions.

Yours,
Arun.

During boot, lots of things other than just drawing the display are
happening, mounting external filesystems, initializing the network,
etc.
There's no way that we can predict which of those or of the many other
possibilities might be causing the load on the processor. Build a
debug
build of the OS and see what debug messages you see while things are
slow is
all I can suggest...

Hai Greats,

Platform :
SW : Windows CE 5.0.
HW : 400MHz DBAu1200 Board (MIPS II platform).

Problem : The display rendering is slow as soon as the OS is up and
running. After that (say 3-4 mins), the display seems to be fast. So,
there exists an inconsistent UI response (speed and slow).

What will be the root cause for the above problem ?.

Thanks in advance.

Yours,
Arun.
