The emojis are pixelated

Emojis are pixelated when moving the main display and using a frameless window.

Please find attached a sample project "emojis-pixelated-project.zip" to reproduce the bug.

Please find attached the executable "emojis-pixelated-executable.zip" built from the sample project.

Note that I have tried by setting a frameless window using Qt and Windows APIs (both give the same result)

Requirements:

Two monitors configured as follows:

Multiple display settings: Extend these displays

1. Display I

    1. To the left of Display 2

    2. Resolution: 1920 x 1080

    3. Scale: 100%

    4. Display orientation: Landscape

2. Display II

    1. To the right of Display 1

    2. Resolution: 3840 x 2160

    3. Scale: 300%

    4. Display orientation: Landscape

    5. Main display

Reproduction Steps:

1. Unzip the sample project.
2. Open the location where the application was unzipped and move the explorer window to Display I (the non-main display).
3. Open `emojis-pixelated.exe`
4. The window will first appear on Display I and then, after a few seconds, automatically move to the main display (Display II).
5. Notice that the emojis are pixelated.

Good to Know:

To make a comparison with the expected behavior, you can move the window to Display II (the main display) and open emojis-pixelated.exe from there. Since the window will not move from one display to another, the emojis will be sharp.
