Subject: [PATCH] GDK W32: Use PROCESS_PER_MONITOR_DPI_AWARE
|
||
|
|
|
||
|
|
According to Microsoft documentation, PROCESS_SYSTEM_DPI_AWARE, just as
|
||
|
|
PROCESS_DPI_UNAWARE, allows Windows to scale GTK windows and do all kinds
|
||
|
|
of stuff. To ensure this doesn't happen, we need to use PROCESS_PER_MONITOR_DPI_AWARE,
|
||
|
|
even if GTK does not really handle DPI changes dynamically via the WM_DPICHANGED
|
||
|
|
message.
|
||
|
|
|
||
|
|
This completely prevents Windows from scaling GTK windows when they are moved
|
||
|
|
between screens with different scaling set up.
