TListView scroll, ugly performance on High DPI Windows

[Diego Simonini 1]

Hello, I'm novice to FMX development.

I'm doing tests with a FMX app on a Windows tablet, basically a simple list of data to be scrolled.

Given that the FMX TListview scrolling performance in Windows is basically very poor compared with the same app running on Android....

I've found that in Windows, as the resolution or the DPI increases, the scrolling fluidity decreases until it is completely unusable

For example, given a Windows 10 Enterprise Tablet with a resolution of 2560x1600 and 250% scaling, a basic TListview bounded to a TPrototypeBindsource with a few rows scrolls terribly

With the same hardware, for speeding up the scroll I've experienced two possibilities (always poor scrolling but usable):

1. recompiling with [DPI Awareness = None], but obviously all appears blurred

2. lowering Windows resolution/scaling

 

I point out that the same tablet at the max (recommended by Windows) resolution (2560x1600 - 250%) scrolls beatifully in browser and also in Windows Explorer

 

Some ideas to improve in these situations?

Thank you
