Windows 10: Critical UI Bug: Qt Application Window Fails to Render Correctly on Monitors with 150% Scaling

I have developed a window using Qt PySide6, and I encountered a problem when dragging the window between two monitors. The issue specifically occurs when the secondary monitor is set to 150% scaling.When I drag the window from one monitor to another, sometimes the window display becomes distorted, and only about a quarter of the content is visible. Despite the visual distortion, the window still responds to clicks and other interactions as if the full content were displayed normally. The window returns to normal only after I interact with another application window, such as clicking on it.Ad

Mixed resolution scaling results in blurry applications?

This looks to be a continuation of the bug described here: http://answers.microsoft.com/en-us/...s-blurry/367c746f-1477-4199-b7ae-98f3d2b86cb8.

I have the following monitor configuration:



Monitor #1 is UHD and is using 150% scaling. Everything that respects scaling looks great on that monitor. Monitors #2,#3,#4 are 1080p, 1080p and 1440p respectively, and are set to 100% scaling. The problem is that most things appear obviously blurry
on monitors #2,#3, and #4. Windows appears to be scaling everything on those monitors to 150%, then scaling back down to 100%. Any legacy dialogs and applications that don't respect scaling look perfect on monitors #2, #3 and #4.

If I take an application that does respect scaling (say Chrome or Edge), and place it on monitor #1, but overlap it a little bit onto the other monitors, the application looks scaled to 150% on those other monitors and does not appear blurry.



After fiddling around with connections, I'm convinced that it is not a hardware or driver issue, and that Windows is scaling, then descaling, the monitors I set to 100%, and the results are very poor. Is there any way to get Windows to simply *not* scale at
all on those monitors - to disable it entirely?

 

UI issues on many applications

If I do use lessor resolution than the option of Full HD is useless. Well I will give a try!

About 110% custom scale I have done that and UI had issues again!

I have done that and UI had issues again!

 

Java based application not scaling properly

The developers of the software (Powerschool Group LLC) have not allowed for this Windows 10 UI Scaling, you should get the college to contact the developers and get them to provide a patch to fix this issue . . .

As can be seen from your screenshot, some of the UI components on the Window are scaling and some are not.

This is not a Windows error, it is the responsibility of the developers of the software to ensure their software renders correctly regardless of the screen size or UI scaling . . .
