I think a screenshot would be good. I tried this PR the last time it was suggested, but I couldn't see any changes.

A screenshot is always welcome for this kind of change :)

@jay1109 Could you show us the screenshot please?

As indicated by Yaron10 in the referenced discussion, the problem with this change is that it unconditionally enables ClearType even for those of us who disabled it system-wide. Notepad++ should either replicate the global settings or at least allow us to configure this through the Preferences dialog.

Np++ 6.7.8 without Clear Type . . . . . . Np++ 6.7.9 with Clear Type

I don't found where I can forbid Clear Type for Np++
You see in Tab-header - the same, but in main window - other.
ClearType is disabled in system, but Np++ now have Clear Type

Hello DmFedorov,

I hope this issue would be resolved in the next version.
A workaround for v6.7.9:

Install the Notepad++ Python Script plugin.
http://sourceforge.net/projects/npppythonscript/

Add the following lines to the file startup.py.
editor1.setFontQuality(0)
editor2.setFontQuality(0)

Open Python Script -> Configuration.
Set Initialization to ASTARTUP.

Best regards.

See #311.
