Windows have strange performance when dual monitors are used

[Arvin Staff]

Hi,

Recently I noticed several issues regarding the window's strange performance on dual monitors.

Environment:

Windows 10 20H2

Display 1 (main): 2560 * 1440 - landscape

Display 2: 1080 * 1920 - portrait

Syncfusion WPF UI V19.1.0.55 (NuGet)

Project using .NET Core

Issues on the main display monitor:

1. Maximised size not correct (Plz see Figure 1 in the attachments)

2. "CenterScreen" works improperly (Figure 2)

These issues also exist in the local demo view and the theme studio window of Essential Studio 19.1.0.54

Exceptions:

1. The performance is strange on dual monitors because everything works fine if I set "Show only on 1/2" in the system settings (Settings - System - Display - Multiple displays).

2. I have also found that if I set ResizeMode="NoResize", then neither issue would exist. However, it is not feasible to do it to all windows in my project.

Could you confirm these issues?

Regards,

Arvin
