Why does my excel window lag so much when moved around the screen? no other app windows have the problem

Here's a direct link to my MS feedback which was made using the "share" feature in the app:  https://aka.ms/AA6d6bd

This link will open the feedback hub app directly to my feedback item.

I just sent feedback on this subject to MS using the Windows10 "feedback hub" applet.

To upvote my feedback item by running the feedback hub applet, do this...

1. In Win10 run the feedback hub applet
2. find my feedback using the search box at top of applet.  This search box isn't labelled.  Its just the box at the top of the main screen.  Type keywords then click the magnifying glass to search.  I titled my feedback "Excel on Win10 slow awkward window movement", so a subset of those words works well, like Excel awkward .

3 Click the "upvote" link.  (Its small and not obviously a link.)

I think its best if we have one feedback item with a lot of upvotes, rather than many separate ones which my not get collated.   Feel free to submit your own, or comments to mine, but please upvote mine, to help us get noticed.

The root of the problem is the way Excel is programmed to write the application to Windows.  The key to remember is that EACH of the "Office" programs was designed and built independently MANY years ago. So the design and code was specific to the needs of the application.  So, yes, I agree while A work-around to the problem is reducing mouse scan rates, the actual problem is in Excel itself.

But the reply to your last question

So... @Microsoft reps, any chance you would approach the problem seriously?

is this is the wrong place to be asking it!  You need to submit a "bug report" feedback to MS. The more people who use feedback to complain about this problem, either by tagging on to an existing feedback or by creating a new one , the more likely MS is to act on the problem.  It helps if you are in a business situation and you can explain the business cost of this problem.

As I noticed the same problem (I'm using desktop computer) I tried many methods mentioned here, like turning off hardware acceleration, one-note synchronization, reinstalling and so on. Nothing works.

I'm also using high frequency/resolution mouse and I tried also lowering it - I admit, lag get less noticeable, but one thing I do not understand is why this is happening only in excel (for me at least, apart from excel I'm not using outlook, just acccess, word and one-note) and why only when I open spreadsheet (even empty one).

This is somewhat counter intuitive to linking the problem to gaming mouse only - seems more like bug in the excel code.

So... @Microsoft reps, any chance you would approach the problem seriously?

PS. Some basic system info below

Recently there was a lagging issue related to "gaming" mice.  These mice have a "high" scanning rate (1000+ times per second vs 100 times per second) meaning they can track MUCH smaller moves of the mouse. Useful in games, NOT for Office. Some people found reducing the mouse scan rate, usually to the minimum, helped with their problem.

Some mouse drivers allow you to set separate profiles by application.
