This reverts commit9151bb7b9e. This reverts commitac4dce1c20. This reverts commit754b72d155. In order to make the fix work, we need to redirect the client window instead of the frame window. However, we cannot to do that because Xwayland expects the toplevel window(in our case, the frame window) to be redirected. Another solution to the texture bleeding issue must be found.
