Window animations start flickering after some time

I have just installed Tumbleweed on a Lenovo E125. Immediately after first login the window animations were flickering and also some windows were not drawn fully when restored from panel. Disabling and re-enabling compositing with Alt-Shift-F12 solved the problem for some time, but it started again. Disable/enable again solves, but repeatedly the problem comes back. What is the problem?

Here is a video about the issue: [video]https://drive.google.com/open?id=0B0z8dQ0f-Yc4dXg2emUxWHRuS1k[/video]
