[Title] Fix to noise DRI2 buffer.

[Problem]  When window is created and is shown first, noise is appeared.
[Cause]    When window is created and try to render at first, canvas size 1x1, but DRI2buffer size is bigger than canvas size.
[Solution] If canvas size is different to DRI2Buffer's, skip swapbuffer.
[Team]     Graphics
