Hi,
I am using Win10 on 13.3" 1920x1080 display.
When I'm choosing the recommended display size of 150% my icons on the desktop and task manager become blurred.
(see attached picture, in red).
I don't know if you can see it in the picture but if I'll change the setting for 125% and then to 150% the icons become sharp until I log out and log in again.

I don't fully understand the issue yet but it has to do with some applications not being designed to support DPI scaling. I have this same issue on one of my machines. Either you leaving scale at 100% and it looks great or you can increase the scaling and you get blur. I don't like the 100% though because my eyes are terrible and everything is tiny on a 13.3 inch screen. The solution apparently is to disable display scaling for certain applications. I'm in the process of working out the issue myself. If I figure it out, I will report back.
Each icon is in reality a collection of images designed to look best at different resolutions. Some applications take this seriously and indeed provide a number of icons to be used at different resolutions. Other applications don't care much about that and just provide one low-res icon.
In your case it means that these specific applications (whose icons are outlined in red in your screenshot) did not bother to provide large (high-res) versions of their icons. This means that Windows has no other choice but to take the regular (low-res) version of the icon and stretch it to larger size. This is what make them look "blurred".
Other applications did provide high-res versions of their icons, so they look fine in your screenshot.
So what is the solution? Just use third-party icons?
Either live with it, or go to shortcut properties and indeed specify some third-party icon instead (like some Windows built-in icon or whatever you want).
BTW, just in case you might want to try to rebuild the icon cache, just to see if some Windows glitch is involved here. But I find it unlikely.
I didn't spend $1000 on a high resolution display to "live with it". I'll start with changing the icons but if I remember correctly some application in general have issues with scaling. The article I read the other day suggested disabling display scaling on high DPI settings for specific applications that will allow it. Again I have not experimented with this yet but I plan to.
Create your own(like I do to customize).
Get an image you want to use, open up Paint resize it to 256x256 pixels, save as png, then to convert to ico go here: ConvertICO.com - Convert PNG to ICO and ICO to PNG
place the ico in a custom folder for ico, THAT WILL NEVER BE MOVED(real important), right click the offending shortcut icon, if offered go "open file location" and change that one icon to change all instances:
(usually in C:UsersYourNameHereAppDataRoamingMicrosoftWindowsStart MenuPrograms)
or
(C:ProgramDataMicrosoftWindowsStart MenuPrograms)
Or else change just the desktop icon.
To do this just open up it's properties, shortcut tab, change icon. Then work your way to where you put your newly created icon and choose it, click apply, click ok, done!
Note if you evermove or delete the ico from where you stored it,the shortcut icon will revert to a default sheet of paper icon.
