Recently the flashplugin leaves artefacts on the screen. That is I see contents of flashplayer-videos in black surfaces (that is text, images and videos). I have this behaviour with 270.18 of the driver, as well as with 260.19.04 (I switched to 270.18, as the latter had some odd pixel artefacts when scrolling after playing some videos with vdpau in mplayer, which made the screen unusable).
Is there a way to remove these artefacts without restarting X?
OS: FreeBSD 9.0-Current,
Driver: 270.18 with twinview.
