Adjust layout of iw3 desktop

[laiyangli001]

The size of iw3 desktop -processor layout is too small,could you change to more bigger like iw3?

It seems to be UI scaling issue (Scale and Layout in Display Setting).
The problem is that the combox is set to a fixed size (200, -1).
However, when the scaling is greater than 100%, the text becomes larger, making the combo box appear smaller in comparison.

The issue occurring only with iw3.desktop is due to the DPI awareness level set via SetProcessDpiAwareness(2). This is used only in iw3.desktop because it's necessary to correctly render the mouse position within the screenshot.

I will see if I can adjust it to fit the display setting.

Fixed in dev branch.
I have only been able to test it with 150% scaling but it is probably working.
