When playing windowed mode with 3D acceleration enabled, the window seems to freeze on an image, and does not refresh or show animations, while the cursor seems working fine, activating on the expected places and accepting inputs. When moving the window, the image is refreshed (p.es.: if I clicked where the menu button should have been, nothing is shown, but when moving the frame updates showing the menu opened)
This does not happen if fullscreen is enabled, or 3D acceleration is disabled. It seems to be peculiar of a window with 3D enabled.
