ghost images/trails of windows when moving
I installed the latest 1.2 version of the driver today.
I'm using Linux Mint 18 with Cinnamon. When moving windows over the desktop there are ghost images of the windows. In the earlier version my mouse had ghost trails. |
Hi,
Is this also visible on a screen shot captured with Print Screen? If yes, then the compositor already messed up the framebuffers we take pixels from. If screenshot is fine, please collect logs and attach here. If it's not, try with a different window environment. Thanks, Michal |
I have the same issue
Hi
I have the same issue. I am using Ubuntu 14.04 , with 4.4.0-38-generic kernel. The issue happens mainly when I use Gnome 2 and the screen shot does not include the ghost windows. Actually when doing the screen shot the screen is refreshed and the ghost window disappear. They come back when I move any window. When using Unity I cannot reproduce it but then I get 200% CPU consumed by Displaylink Manager (I have the same issue with the older drivers). I went back to 1.1 version for now. |

Seems to be a driver issue (Intel). There a 4 messages per second in dmesg.
Due to a display-id which isn't recognized (I think less than 1). |

I have the ghost images/trails issue with all 1.2.* drivers (not with 1.1) but I don't see any error in dmesg. You can find a screen photo here: https://drive.google.com/file/d/0B-X...ew?usp=sharing Thanks |
@maximih: could you check a screenshot as well? (not the photo) It would show if the framebuffers are fine. Also, please attach the logs captured with Linux Support Tool so we know what kind of environment you have.
Cheers, Michal |

See attached the screenshot and the support tool output. |
Hmm. Can you ssh to the machine and try to capture a screen from the console? (assuming it won't redraw full screen before taking a grab).
Or, alternatively, if you're willling and have time - you could perhaps try `monitorsim` from https://github.com/mlukaszek/evdipp/. Firstly, it would show if similar corruption can be reproduced with any evdi client, but also - this makes screenshots every 10s and saves it to a PNG file. Cheers, Michal |
