**System Information**
Windows 10 and GTX 970 (newest drivers)
**Blender Version**
Broken: 2.76
**Short description of error**
On **some** computers (IRC #blender verified) it seems that turning on the** International Fonts** option in User Preferences -> System causes the middle mouse roller zooming in Node Editor to slow down considerably.
`Ctrl MMB` or even `Shift B` zooming still works fast even with **IF** on. Altough in high zoom scenarios it slows down too when compared to **IF** off.
**Exact steps for others to reproduce the error**
`Ctrl Alt U`
System -> check "International Fonts"
