    Yes. Its the same old story: lots of different Macs, triggers, theories, no-work ideas, extreme irritation. If everyone having mouse problems sent a complaint to Apple's feedback site, perhaps every time that the problem struck, they (might) pay attention.

    Latest Mac Mini, wired Apple Keyboard, Wireless trackpad, OSX 10.8.1.

    had zero disappearances until I ran Lion Designer 3.3.

    Command-tab sort of works...  the mouse cursor appears in the other app, but come back to this one (Chrome) and it's gone again.

    The only reliable way I have found to get the cursor back (for a little bit) is two-finger tap (Secondary Click)

    Almost never use Launchpad or Mission Control.

     

    Curious, I just tried Launchpad after discovering that moving my cursor all the way right (where my Dock is) will make the cursor re-appear. Anyway, in Launchpad, the cursor is unpredicatable. first time it wasn't there at all (except on the dock), second time it was there, then went poof.

     

    So very bizarre.

    Noticed it happened mostly in Chrome.

    Have restarted chrome and have no lost the cursor since.

    Can we blame Chrome instead of Mountain Lion?

    It's not chrome. I don't use it, and many people report this happening in other apps such as Safari.

    Yes and both Chrome and Safari uses Flash. Other people have reported that it happens when working in or upgrading Photoshop. Both are from Adobe and I wouldn't be the least bit surprised if there's some Flash components in Photoshop or if Adobe silently upgrades Flash when you install Photoshop.

     

    It has never happened to me untill the day last week when I upgraded Flash. Then it happened three times just that day.

     

    I have found a solution that works for me: Go to System Preferences -> Accessibility -> Zoom -> activate "Use scroll gestures with modifier keys to zoom".

    With that, CTRL + zooming in/out on the trackpad brought back the mouse cursor for me.

     

    EDIT: And when I started suspecting Safari/Flash, I closed Safari every time after browsing (for some reason it seemed to happen only when the Mac was not in use and I came back after some minutes/hours to use it, never when actually using it). Then the problem went away untill I left Safari open as a test.

    Suddenly the mouse cursor disappeared again.

    I just experienced this problem in Safari.  Mountain Lion Macbook pro early 2011.

    Hello,

     

    I solved this problem temporally and I think it's not so hard to use it.

     

    The whole problem is about switching desktop using gestures or keyboard shortcuts, not about mission control.

     

    So I deactivate mouse / touchpad gestures and keyboard shortcats and I use Mission Control.

    It's a difference and limitation but it isn't so bad. It's slower but usable.

     

    Btw: I recorded a video with this bug.

    I have a mac mini running Mountain Lion and iMac running dual monitor on Lion. Both computers have this same problem of the mouse doing a disappearing act, On the iMac Im not too bothered about the problem I just hit cmd + tab and the mouse reappears, I can live with that although really shouldnt have too.

     

    The mac mini is brand new straight out of the apple store, im using it as a media center on the TV so its only got Plex installed I dont have a keyboard attached, this seems to be a massive problem as once its gone theres no getting it back unless you restart the thing? It seems to always happen after I exit Plex which comes from being in full screen mode so I think pdostal_cz is on to something but as I dont have a mouse or touchpad I dont think it can be to do with shortcuts? Is there no script that you can run to get the mouse back or something that doesnt require a keyboard or restart everytime?

    Is this the only forum in the world that doesn't take you back to the topic you were viewing when you actually sign in? lol,,,

     

    Anyways, I have disabled the accessibility->display->cursor size feature I had cranked up for the mouse cursor since I am using a 27" cinema display and really everything is just too small on it at the default settings and since then I have not had the cursor disappear at all.

     

    I am suspecting this bug occurs whenever anything changes the cursor size or perhaps the cursor itself as some applicaitons do, like full screen mode, etc.

     

    Try simply putting the mouse cursor size to 'normal' and see if it continues not using any fancy apps just the normal OSX and its apps.  If this works for you for more then a day I think we found the issue.

    I think we have a winner. I just set the mouse cursor size to 'normal' and I have not lost my cursor in three hours and counting.

  • 41. Re: Mouse cursor disappears.
    groovyd Level 1 Level 1 (0 points)

    Yeah, I really think this is it. 

     

    Something in their cursor size code is getting lost during render.  I suspect any size except for normal causes it to require hardware accelerated resources to resize the cursor bitmap and it is getting deadlocked doing this resize by another process.  Most likely a priority inversion.

    Not necessarily. I just checked my Mini, and the mouse cursor was and has always been set to 'normal'.

    Still haven't lost my mouse cursor ever since I reset it to normal. Running ML on a 2010 Mac Pro.

    I have 'normal' as a default setting, so in my case it just isn't the solution unfortunately.
