The curves of the letters are not smooth.

When exporting to jpeg, tiff, etc., this problem is quite unpleasant.
I found out what was happening. When the text is filled with a solid color, everything is OK, but when filled with fountain fill, the letters are deformed. I think this is a bug of CorelDRAW, not fonts, resolution or antialiasing
can you attach a file sample for test it?
