On a fresh install it was lagging when switched to full-screen dash(after a fresh boot with no applications running and letting the OS to load fully and with 1 minute of additional time for any operations it might have to do to finish). After I updated it wasn't lagging any more when it was full-screen. I can't test if the MeMenu lags because now when I open it(MeMenu) Dash closes automatically.
I tested with a video in the background, for that I opened Firefox with 1 tab with a youtube video loaded. The video set on 480p, it was enough to start the video for the dash to lag very hard in FullScreen mode or Non-FullScreen mode and also the video was lagging while the dash was open... I want to remind that this laptop is not that weak, it can play without any problem 1080p youtube videos for example. Also, if allowed, why I said it has a bad performance impact: I had a long time ago a PC with AMD Athlon 3000+(1 core, 1 thread, 1.8 GHz) and 1 GB Ram and it was running without any problem Windows 7 and KDE. This laptop is about 2-3 times more powerful than that old PC that I had and it lags when it opens the dash and the computer does any other operations while the dash is opened... I also want to point out that this laptop has Kubuntu 12.04 LTS installed and it has no problems at all with all the default effects activated... I can compile the kernel on it with -j16 and youtube videos don't lag on 1080p in KDE. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/839384 Title: [Oneiric]Unity Dash has a very bad impact on the computer performance To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/839384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
