compton × screensavers

Hi all, I tried to set the compositor to compton-tde and now instead of screensaver Clock shows only black screen. In the test, the Clock is displayed correctly. When I set the screensaver to Swarm, the bees appear, but background is not erased - bees appears on the desktop background image. With screensaver Science displays the background image, but it is not visible any further activity. Some screensavers do not show problems - Fiberlamp, Galaxy. Anyone notice the same behavior? -- Slavek
