I have created a table dynamically and then use Report/Perform() to display/print the report. However, sometimes the borders display and other times they do not. If I resize the window it changes which borders appear. Sometimes you can get it just right so that all the borders appear.
Excuse the longer example but it has QTF code to show the problem:
It is because it scales down too much -> the width drops bellow 1 pixel.
Interestingly, there is simple way to fix the problem - add Painter package to your project. That will activate high-quality subpixel accuracy software rendering of Reports and thin lines will be drawn just fine (as gray).
