Random Mouse Stutter/Lag Windows 11

Thanks for your response. I am running an SSD as drive C and a spindle for D.

That said when I took my mouse apart I found a substanial amount of debris in and around the left button switch. I used some compressed air and alcohol to clean it. It has been fine for a couple of weeks now.

Yes, it is very important to clean your mouse to keep it healthy and happy. In fact, here is an actual memo in IBM for properly attending to your mouse.

Abstract: Mouse Balls Available as FRU (Field Replacement Unit)

Mouse balls are now available as FRU's. Therefore, if a mouse fails to operate or should it perform erratically, it may need a ball replacement. Because of the delicate nature of this procedure, replacement of mouse balls should only be attempted by properly trained personnel.

Before proceeding, determine the type of mouse balls by examining the underside of the mouse. Domestic balls will be larger and harder than foreign balls. Ball removal procedures differ depending upon the manufacture of the mouse. Foreign ball can be replaced using the pop-off method. Domestic balls are replaced using the twist-off method. Mouse balls are not usually static sensitive. However, excessive handling can result in sudden discharge. Upon completion of ball replacement, the mouse may be used immediately.

It is recommended that each replacer have a pair of spare balls for maintaining optimum customer satisfaction, and that any customer missing his balls should suspect local personnel of removing these necessary items.

To re-order, specify one of the following:

• Domestic Balls - p/n 33f8462
• Foreign Balls - p/n 33f4861

Apparently this was written as a serious memo....I just find it fun to read! LOL

Agreed that apps should not be coded where the UI is blocked, however, the OS is supposed to isolate that to the application not system wide. This particular issue (for me anyway) seems to be across applications, which would indicate that the problem is closer to driver, OS or hardware level than application level. These types cross application isolation and would affect the entire system.

Why don't you just try a different OS now or check it outside of Windows? If it goes back to working fine outside of Windows 11 then its related to Windows 11.

But, applications should be coded to not block the UI thread. Eg, networking isn't supposed to block, delay, or otherwise mess with the UI. This is good programming. If an application does it then they hired a bucket head to do the work or the code they used doesn't work very well lol. Of course, I can point to various software around that does block the UI thread so there are devs who do this stupid thing. But, that's one application, not all or multiple of your daily bunch.

I have both an SSD as my main (C:) drive, and HDD drives. Happens no matter which drive it is writing to. I had this same problem with a Windows 10 machine that I bought last fall, and I returned it after the manufacturer was unable to find a solution, so I don't think it's a problem unique to Windows 11. My 3 year old machine works like a dream, and I can't figure out where the difference lies . . .
