How do I receive finer delta values "ultrahighresolutionscrollingaware" when scrolling using my logitech mouse which supports smooth scrolling. I am able to smooth scroll on all browser using it, but when I scroll in my app, I only receive (+/-)120.
When I scrolling using the touchpad in my app, I receive finer delta values ( close to 1 ).
What do I need to set or enable in my code to receive smaller delta values when scrolling using the logitech mouse?
How are all the browsers able to do? Please help...
One thing I noticed, if I set chrome or edge as the foreground app (top-most) and point the mouse at my app and scroll using the mouse, then I receive ultra high resolution delta values. Then my app smooth scrolls.
I am on Windows 11, and coding using VS 2022.
I also tried setting
<application xmlns="urn:schemas-microsoft-com:asm.v3">
<windowsSettings>
<ultraHighResolutionScrollingAware xmlns="http://schemas.microsoft.com/SMI/2013/WindowsSettings">true</ultraHighResolutionScrollingAware>
</windowsSettings>
</application>
and it did not help.
Can you provide a minimal sample to test? Does not contain any personal privacy.
The issue is reproducible with these samples:
Just build them and run.
If you make these apps the background app while edge or chrome is the foreground, you will start to receive high-precision deltas. You can check with spy++ as well.
Btw, I am using Logitech MX Anywhere 3.

Thanks.
Have you tried this manifest? https://learn.microsoft.com/en-us/windows/win32/sbscs/application-manifests#highresolutionscrollingaware
I tried "highResolutionScrollingAware" as well.
It only seems to affect the scrolling via the trackpad.
When scrolling via trackpad,
if I set "ultraHighResolutionScrollingAware" to true, I get delta = 1
if I set "highResolutionScrollingAware" to true, I get delta = 40
if I set "ultraHighResolutionScrollingAware" to false, I get delta = 120
When scrolling via the logitech mousewheel ( smooth scrolling enabled ), I only receive delta = 120 for any of the above settings. (Unless the browser is in focus)
Do you have the same results when you test it on other mice?
Sorry, I don't have another mouse by a different manufacturer to test with.
I have only tried with a logitech mice.
Hello Hari-1269
In this case, it seems that you are using the manifest correctly, but for some reason is not taking effect,
I would recommend to send a feedback to the Visual Studio team to collect more information and help with the issue:
