@nirzaf - we had seen similar issues in multi-monitor setup, where the primary monitor has resolution other than 100%. What screen resolutions do you have?
Why do you think this is related to the Core SDK version? What version is your application targeting?

[nirzaf]

I am using a single monitor in my laptop ThinkPad i7, with resolution 1366 X 768 (Recommended by Windows 10) My targeting .NET Core SDK Version is 3.1 LTS Version

I'm sorry, I meant to ask what your scale on the primary monitor was, could you please lookup it as well:

Why do you think the issue is related to .NET SDK, what happens when you switch to NET 5.0?

[nirzaf]

I couldn't find any options called Scale & Layout in my windows settings

[Tanya-Solyanik]

Hm, had you tried typing "scale" in the search box on the upper left? Had you looked in the "Advanced" link?

[nirzaf]

Yes, I tried all the possible way to find that option but could not find it,
I am using Windows 10 Enterprise Version 2016 LTSB, Updated always, I had this problem in previous visual studio versions as well, but Previously I didn't even get that white blank screen After updated to 16.6 I get this white blank screen
