Question / Help WPF Applications + Window Capture not working

[lfvideos]

Hi, i made a WPF app for Twitch that captures the chat and lets the streamer know when they get a new subscriber and pops up a message on screen.
Sadly, i've been unable to use OBS window capture on it.
When i open the window capture screen, it just doesn't show the window at all... i tried 32 & 64 versions for it but it doesn't work.

Here is the link for the app if you want to try yourself:
https://app.box.com/s/lt6otg3xykf1vs8kfq2d

It was coded on VS 2010.
Its on C#
Using WPF

What i need to do is to window capture only the green area.
Some streamers have been reporting that window capture actually makes them lag a little bit so window capture seems the way to go in this case.

I also tried with new windows and projects (to make sure its not a project issue) that only had a button etc, nothing fancy. Still not working.

Any ideas?
Thanks.

Try using "Capture layered windows" in window capture. If it doesn't work otherwise I'm not sure what to suggest. It probably has something to do with transparency on the windows, or the windows being drawn directly with direct3d.

As far as i know WPF does indeed use direct3d nativelly but i think there is no way to change it...

On the OBS window capture, even capturing layered windows it wont come up in the comboBox.
It doesnt detect it as a window...

Do you think there is a work around this?

EDIT:
There is no transparency effect at all, the window is plain an simple.

Not entirely sure what to suggest as an alternative to capturing it for the time being unfortunately. It'll require some more investigation
