After about an hour of gameplay, my mouse becomes distorted and forms a shape like a steel grey comb or rake, with the teeth facing left to right. When this happens, I loose control of game, because it become difficult to use the mouse pointer with any precision.

I have recently upgraded graphics cards and changed drivers, but I have now experienced the same problem with both cards, which leads me to think that it is not a GPU problem.

Any ideas what could be the cause?

Do you have a logitech mouse? If so, delete the 'setpoint' drivers and software. You don't need it and it can conflict with game pointer settings as well as Windows settings. Windows 7 controls are all you need.

No, I have a wireless keyboard mouse combo from Microsoft.

 

Thanks for your thoughts anyway.

Could the distortion of the pointer be a sign that my GPU is overheating?

Because a game of Company of Heroes can run for over an hour, it maybe that the temperature inside my PC case is getting too high. Is this sort of distortion associated with overheating?

It's used to be a known problem with old ATI drivers and Win 7 x64 in certain applications.

What driver version are you using?

Can you update further?

Try uninstalling ATI drivers and just use the Windows ones. See if the problem persists.

 

And no mate, it's certainly not due to heat.

If I'm not mistaken, you may have one of those infamous Gigabyte motherboards which had this issue until a BIOS update solved it. Do you have the latest BIOS for your board?

I have that probblem too, mi motherboard is gigabyte, It was updated yesterday, but the problem persists, i Haev AMD 7750.

-------------------------

It's an old bug with AMD drivers, which they "solved".  I still see it from time to time, but it fixes itself after a very short period of time, usually after I move the cursor to the second monitor (where the cursor appears normal) and back a few times.

I don't know if moving between monitors has anything to do with it, or if there's a periodic cursor reset that fixes it regardless.  But if the problem doesn't go away on its own, I'd suggest filing a bug report, to encourage them to fix it properly.

 

I'm having this same problem with a multi monitor setup.  Running HD7700 with three monitors on a newer Intel i5 processor and Asus p8z77 mb. 

Anyone actually solved this problem recently?

I have the same problem.Weird thing is i run on two monitors and if it does it on one monitor it doesnt do it on the other.So i can drag pointer back ands forth and one monitor has comb and other pointer..

Yes it isn't hard to get rid of, usually takes 10 seconds or so.  But it is still a huge nuisance.  From a little internet research it seems like this has been a problem with multiple monitors on AMD video cards for years.  I'm surprised there hasn't been a fix.

This is mouse cursor corruption due to Radeon Card + Multiple Monitors

From what I can tell this problem has been around as early as 2003

After 10 years there have been no solutions

One temporary fix is to enable pointer trails, this causes windows to constantly re-draw the cursor

This issue is also caused by hardware acceleration...try using software. In Ie go to tools>internet options > advanced and select software instead of gpu. Firefox has the same settings. Only takes a minute to find out if this solves the problem.

I am seeing this same problem in a business enviroment, so no gaming going on.

We use PE builds of Windows and recently were attributing the problems to that particular build.  We just discovered that it is not isolated to that version of Windows.  Below are several of our test cases and specs to follow.  Any ideas are appreciated.

 

Test 1 - PE build with latest drivers will run for approx 24hr before mouse distorition occurs, enabling mouse trails makes pointer look correct, however with or without mouse trails, when doing any form of reboot/shutdown, the computer only goes down partially and a hard power is required to take it all the way down.

 

Test 2 - PE build with latest drivers from HP (older than AMD release), same symptoms above

 

Test 3- Non pe build, same symptoms as above, however, time before failure is >5 days.  With this version we currently have 10 identical machines running with differents levels of our internal software, including no internal or 3rd party software, to full 3rd party/internal software.

The problem is that all "solutions" or others with same issues are occuring on gaming systems and most can be fixed with a little mouse jiggle, whereas our machines are idle with no user interaction and only resolve with a reboot or unistalling video drivers within windows.  Once video drivers are uninstalled, pointer returns to normal, reinstall drivers, pointer is normal.

In all of the scenarios windows does not detect a "problem" and aside from being unhappy that we did a hard power, it is oblivious to the problem.
