Our automatic signature tool creates signatures for all our employees. The signature works fine until people with non-100% dpi setting on display (e.g. medium 125% or Larger 150% in Control Panel > Display) try to edit their generated signature and saves. Suddenly the images get resized and blurry, even if it is not displayed as resized when save the updated signature.
It works fine to edit and save if you have display DPI set to 100%.
The company logo is 127x38 pixels, 2,15KB GIF file.
Is this a known bug or something else? I'm not sure its fair to blame the signature-tool as it works okay before the editor has been doing its stuff.
Another strange thing. If I have edited a signature in 125% and saves it. I send an email and the signature logo is blurry. But if I change display DPI to 100% and send another email (logoff and logon first to change dpi) then the logo is fine again.
Seems like the logo is bound to text size
Update: seems to only happen on GIF-images!
