ChromelessWindow control uses a lot of memory and CPU.

[Ebsan Uddin]

Hello,

I'm trying to work with the ChromlessWindow control but I noticed that when I run it my app uses a lot of extra ram and CPU. I replaced the ChromelessWindow control with a regular Window control and my app is stable at about 2.5% CPU and about 30MB of RAM. With the ChromelessWindow my app uses about 5% CPU and 80-100MB of RAM. This seems like a lot of CPU and memory usage for a simple class. I think it might have to do with the control loading all of the resource dictionaries for the skins but I'm not sure how to fix this. I really only need the Metro skin. Is there a way to use the ChromelessWindow control and load only the ResourceDictionaries that I want? Or is there another issue making this control use a lot of resources?

Thank you for the help,

Ebsan

Hi Ebsan,

Thank you for contacting Syncfusion support.

We have checked your reported issue in a simple sample by comparing MS Window and our ChromelessWindow. But, we can’t find much difference between ChromelessWindow and MS Window. Can you please provide more information about your issue and like whether you are using any other property or controls with ChromelessWindow as it would be very helpful to resolve your issue earlier?

Please download the sample from the following location:

Hello Mariappan,

Thank you for the attached video. I'm placing some custom controls inside the window. I've attached an altered version of your sample app with two windows. MainWindow.xaml uses a ChromelessWindow and NormalWindow.xaml  used a regular WPF window. You'll notice that the normal window uses about half the CPU as the chromeless window. Should this be expected?

We have checked the reported issue in Window8.1 OS but we can’t find much different in between Syncfusion ChromelessWindow and MSWindow. Can you please share your environment details like OS, .NetFramework version and also Syncfusion product version which you are currently using.

Hello,

I'm using a recent patch of the Syncfusion suite, v 13.1.0.21. I'm running Windows 8.1 Pro and I've attached a couple of screenshots including my machine specs and the mem usage with the sample I attached with my previous reply.

Okay, I did a little more testing. So the ChromelessWindow seems to use a lot of CPU when it isn't minimized but you're focused on a different window. So for example, the chromelessWindow app uses around 10-12% CPU when it isn't minimized but I have my focus on the Task Manager. When I click on the ChromlessWindow to focus on it, the CPU percentage goes back down to a normal 2-4% CPU. Can you try to switch focus between the ChromelessWindow and another screen (without minimizing the ChromelessWindow) and see if you get the same high CPU usage?

Thank you again for looking into this issue for me. The app I am creating is mission critical and we need as much CPU cycles as we can to spare to data intensive operations. If the ChromelessWindow is using 4-6% more CPU than the MSWindow then we might have to switch out the window control.
