[Linphone-users] Please enable DPI awareness on Windows

[Esme Povirk (she/they)]

Hello,

I've noticed that the Windows version of Linphone uses the default
settings for DPI Awareness, which is to render at 96 DPI and have the
system scale it, making it blurry or pixelated on a higher DPI
display. This can be overridden in compatibility settings, and in fact
the UI renders just fine at higher DPI.

It seems Qt supports DPI scaling on Windows already:
https://doc.qt.io/qt-5/highdpi.html

So all that should need to be done to activate this feature is to
provide an application manifest for the exe, as described here:
https://docs.microsoft.com/en-us/windows/win32/hidpi/setting-the-default-dpi-awareness-for-a-process

I haven't tested the case of multiple monitors with different DPI, but
based on Qt's documentation that should also work fine, therefore "Per
Monitor" DPI scaling should be enabled.
