Avidemux 2.6.1 GUI textsize bug in Windows 8

[ericzutter]

In version "2.5.6-1 64-bits" the textsize of the "x264 Configuration" popup is correct. But in version "2.6.1 64-bits" the textsize is wrong.

I have the following configuration :

OS: Windows 8 64-bits
size LCD screen: 52 inch
resolution: 1920x1080
custom textsize (DPI): 200%, checkbox "Use Windows XP style DPI scaling" enabled

See here screenshots that I have made of the problem :
