Mouse cursor flickers while moving around (all programs)

I am having the same problem.

The cursor is flashing and, sometimes, it leaves artifacts.
I am not sure if it may be the cause but it started a little after I installed ScreenHero.

And I am on Sierra.

yes i have this too

i have the feeling that it is somewhat related to a stock streaminig web app based on silverlight

do you use somekind of silverlight web app?

I had the same problem, cursor seemingly randomly changing shapes as I moved it across the screen. Fortunately I was able to associate the start of the problem with some issues I was having with Flip4Mac that caused me to install a Flip4Mac upgrade. After that the cursor started flipping out and I was getting these errors in the Console:

10/19/13 12:41:36.054 PM com.apple.qtkitserver[569]: objc[569]: Class TSSandboxPrefs is implemented in both /Library/Frameworks/TSLicense.framework/Versions/A/TSLicense and /Library/QuickTime/Flip4Mac WMV Import.component/Contents/MacOS/Flip4Mac WMV Import. One of the two will be used. Which one is undefined.

One of the two will be used. Which one is undefined.

I'm not positive, but I believe neither of those are needed anymore since FlipPlayer 3.0 has moved everything into the App Bundle. Anyway, I deleted the folders:

• /Library/Frameworks/TSLicense.framework/
• /Library/Quicktime/Flip4Mac WMV Advanced.component
• /Library/Quicktime/Flip4Mac WMV Export.component
• /Library/Quicktime/Flip4Mac WMV Import.component

And then used the Flip4Mac uninstaller to uninstall Flip4Mac, then rebooted, and the problem went away.

I suspect this problem can be caused not only by these specific double definitions, but also by other QuickTime frameworks that are installed in two different places.

So check your console logs for warnings from qtkitserver and/or qtkittrustedmoviesservice logs and see if there is a problem you can resolve.

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

Isolating an issue by using another user account

If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Eric,

This is incredibly generic advice, only one step removed from "do a clean reinstall of the OS" or "buy a new computer". It seems like you really have no idea what the problem is and are just throwing the kitchen sink at it. Which is fine, except that it has nothing specifically to do with this thread.

Jgro your thinking is incredibly simplistic and a only one step removed from "ignorant."

The point of those steps, as linked, is to determine where to look for the problem.

If anybody has actually seen the problem and solved it, they can provide a specific set of steps to fix it.

However, if nobody has seen it before, then a logical process to determine the cause is necessary, hence the suggestion to determine if it happens in all users or just the one, and then if it happens with third-party startup items disabled.

only one step removed from "ignorant."

A generous appraisal.

I have and and I did. Only after that did Eric post the most generic troubleshooting steps there are.

Not really. The point of those steps is to eliminate everything that makes the OP's specific Mac different from a generic one and see if the problem goes away. You can find those same troublehsooting steps anywhere for any Mac problem. If the problem goes away in Safe mode but comes back afterward, it still doesn't tell you much. It doesn't even mean it's not a hardware problem, as it might be a hardware problem with some piece of hardware that has had its driver disabled. The infamous Spotlight reindexing bug goes away in Safe mode but comes right back. Adding these generic troubleshooting steps to an 8 month old thread seems more like trolling for points rather than genuinely trying to be helpful.

ok

If the problem goes away in Safe mode but comes back afterward, it still doesn't tell you much.

No, it tells you quite a bit. It indicates that you have third-party software that starts at power on that most likely causing the problem. Safe Mode disables most third-party kernel extensions and launch daemons, so if the problem goes away, it just may be those things causing the problem.

Once again you display your ignorance. You can't get points just by posting. The advice would have to be useful enough for the OP to mark the post as either helpful or solved.

I have been having the same problem in Adobe Illustrator CC. Every time I went to edit a node, the cursor would jump all around and freak out. I completely deleted Flip4Mac and restarted. It works just like it used to. THANKS!

I seem to have this problem as well. My curser is flickering when I hover over words in pages, word. It also flickers else where as well. But it doesn't do it all the time sometimes it can just go back to normal. Whats the quickest way to solve this issue does anyone know. I see you have discussed things what is the best option?

No Apple Advisor seems to know the answer.

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.

In the new discussion, try running this program in your normal account , then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read. On the screen with Options, please open Options and check the bottom 2 boxes before running. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply. This will show what is running on your computer. No personal information is shown.

I love you man I can't stand those useless answers anymore

I searched finder for Flip4Mac and it came up under Microsoft Office 2008. I uninstalled MS Office and that fixed the problem. Thanks!
