@EDIT I updated my graphics driver and problem now doesn't occurs!Probably this problem is caused by my graphics card (GF 7300 GT)It's very strange because when i minimize and restore app this problem doesn't occurs!Hello.
Sorry for my bad English.
I am clearing and drawing some vertices on RenderTexture every frame and i am drawing RenderTexture result on RenderWindow.
The image "flashes" every 10 frame.
When i am drawing directly to RenderWindow this problem doesn't occurs.
I downloaded SFML.Net 2.0 directy from the site of course.
The following video shows a bug:
Source code which i am used to make video:

) { RenderWindow window
= new RenderWindow
(new VideoMode
(800,
600),
"sfml test"); window
.Closed += (s, e
) => { window
.Close(); }; RenderTexture renderTexture
= new RenderTexture
(800,
600); Sprite sprite
= new Sprite
(renderTexture
.Texture); Vertex

= BuildCircle

.IsOpen()) { window
.DispatchEvents(); window
