What I did: - start kst, maximize the window on a high resolution screen (for example 3200 x 1800) - create a plot and open the "Edit Plot Item" dialog, click "Edit Multiple" - select the plot on the right and click "Apply" What I expected to happen: - the plot should be redrawn as it was What happened instead: - plot gets redrawn with increased axis line width It took me some hours of debugging to find that line of code, but finally.. the reason for the increase is the line width scaling in method double Curve::lineDim(const QRectF &R, double linewidth) { qreal lw = qMax(qreal(1.01), qreal(linewidth) * (R.width()+R.height())*qreal(1.0/2000.0)); The new width is calculated as a product of the old width and a fraction of some rectangle dimensions. If the window size is large enough, the second factor gets large enough to increase the width with every rescaling. I recommend not to use the old width as a factor.
