We are using a RadRibbonWindow in an application (running on Win 7). When the application starts, there is a lot of black areas where comtrols (RibbonBar, tabs etc.) normally are placed, and when moving the mouse pointer around in the RadRibbonWindow, the controls are showing and the black fields disappear. This also happens if i by using the mouse drags the window so it's size gets smaller or larger.
The problem started after i upgraded to version 2010.2.812.40 of the radcontrols. Is this a bug, or is there something i have missed?

The project is far to big to be sent. Is there a way I can send screenshots?

Hello Roy Halvorsen,
The problem is that we are aware of this issue, but cannot reproduce it. We tried with different sample projects, but cannot get such behavior. We will be very thankful if you try to reproduce the issue with a simplified project.

Hello Roy Halvorsen,
Could you please test this sample project and tell me if it has the bellow mentioned problems? If not, we will be very thankful if you try to modify it (add some of the features from your project), so it reproduces the problem. Also this sample uses the latest binaries, which are coming with some fixes to the RadRibbonWindow, so you can try them in your project.

The testproject works fine here. The difference between my project and the testproject is that I am now using version 2010.2.924.40 (runime version v4.0.30319) of the assemblies and the window loads data into a RadGridView at application startup. My project is far to big and complex (server/client, MVVM, Mef, Prism patterns) so I can not modify the testproject to be using some of my data.

Hi Roy Halvorsen,
Have you tried your project with our dlls from the sample that I sent to you? If you need some other dlls with the same version, just say and I will send them too.

Your dlls acts the same way as my dlls, and yes, I did try your dlls. No change at all.

Hi Roy Halvorsen,
Thank you for your cooperation. Since you cannot send me your project and since we are not able to get this undesired behavior, I will ask you, if it is not a problem, to try your project with the attached binaries.
Kind regards,

Sure I can, but there is 2 binaries missing in the attached files that we are using in the presentation layer, Telerik.Windows.Controls.Data and Telerik.Windows.Controls.GridView.

Hi, Viktor.
Finally I had time to test the binaries. They give the same result as reported. There is still black fields disturbing the window. To remove the black fields, I still have to resize the window, but when it's done the first time, I don't see the black fields until I restart the application again. I also found out that this problem does not appear on Windows XP, or when I am running the application through RDP.

Hi Roy Halvorsen,
I am not sure if I have understood you correct, but do you meant that with the old binaries the problem occurs not only when you start the project, but also sometimes later and with the new dlls the problem occurs only when you run the app?

Hi.
There is no difference between the two sets of binaries. They both have the same problem. The problen occurs when the application starts, and the problem disappear when the window is resized.
Some times, the problem is NOT there when the application is started, but it appears immediately when the mouse pointer comes inside the window. And it disappears again when the window is resized.
After resizing the window, it does not appear as long as the application is running.

Is this problem fixed??
I'm having the same issue, and I'm using the latest version of your WPF controls and the latest internal build.
I've submitted a ticket about this issue today:

Hi itai,

Could you please confirm that you use Q3 2011 and the RadRibbonView ? If you are using the RadRibbonBar this may be still reproducible.

RadRibbonView with the latest Q3 1220 build.
Still reproducible (happens only on a specific machine and almost always happens on our big project.
Managed to reproduce on a small sample project after several Maximize and unmaximize cycles.
I'm not sure what triggers it.

Hi Itai,
We are still unable to reproduce this issue on our side. And I looked at the screencast you posted in your ticket and followed the same steps but to no avail. Since you mention here that you can only reproduce it on one machine, I wanted to ask you if you can share with us the specifications and the setup of this machine as well as the theme applied to the OS.
We will also look into the workaround you found and I will get back to you if we have more information on the case.
Kind regards,
Tina Stancheva

Hello Itai,
I will follow up on your issue in this thread as well, in case anyone else in the community encounters similar issues:
Basically our investigation showed that the issue can only be reproduced on a single computer and setting the RenderOptions.ProcessRenderMode to SoftwareOnly fixes the problem. This makes us believe that the rendering issue that only comes up during the resizing process of the window is caused by external issues like the machine setup and its graphic settings.
