On Windows 10, in the display settings, if we set "scale and layout" to 125%, the performance of plotwidget drops dramatically to the point of not being usable anymore.

Also, the curves are ugly, some are 1 pixel with, others are 2 pixel wide.

Would it be posible to only apply the scaling for icons in the toolbar, texts in the axis, etc, but not for the plot lines ?

In guiqwt we have the same problem with curvewidgets.
