CEGUI flashing

[Lahha]

Hey!

My problem is that CEGUI seems to show only every other frame. Any idea why this is happening?

Here's a video.

Ogre Version 1.8.1
CEGUI Version 0.8.2

Thank for your time and effort in helping me!

Main of rendering thread.

void RenderingThread::EntryPoint(void * param)

   } catch (std::exception &e) {
      MessageBox(NULL, (std::wstring(L"Failed to initialize RenderingThread.\n") + widen(e.what())).c_str(), L"Error", MB_ICONEXCLAMATION | MB_OK);
      return;
