WinUI ListView and GridView not scrollable when moving to a different DPI monitor

[yki5000]

Hi,
2 monitors with different dpi. When i move the application window from the main monitor to the extended monitor, it's only sporadically scrollable by mouse scroll wheel (not scrollbar), felt only in 1% of cases. Can anyone reproduce it?

Unpackaged WinUI 3

C++ Windows SKD 1.1

Windows 11

PS: If i move it back to the main monitor, it works as expected :(

PS: I've bought 2 new monitors with a higher resolution (daisy chained) and it's the same problem. The monitor before only had 1920 x 1080.

• My laptop has 1920 x 1080
• New monitors have 2560 x 1440

I bet this will occur more often, if WinUI is really be used for business applications.

This is what i'm using, subclassed.

`
case WM_DPICHANGED:
{
// Resize main window for DPI change.
auto const* const prcNewWindow = (RECT*)lParam;

			SetWindowPos(hWnd,
				nullptr,
				prcNewWindow->left,
				prcNewWindow->top,
				prcNewWindow->right - prcNewWindow->left,
				prcNewWindow->bottom - prcNewWindow->top,
				SWP_NOZORDER | SWP_NOACTIVATE);
			break;	
		}

`
It doesn't occur, if i don't use the WM_DPICHANGED.
