Reproduction: scroll table to the right, then export image, and the first two rows in the exported image will be out of alignment with the rest. In larger tables the issue will be more pronounced, up to having the lower rows invisible.
Browsers: Chrome 74 and 76; Firefox 67. Edge doesn’t appear to be affected.
Flexmonster versions: 2.7.5 and 2.6.14.
Thank you for pointing this out to us and for providing steps to reproduce the issue.
Our team is currently working on a solution to this problem and the fix will be available in the minor release with the ETA 3rd of June.
We kindly advise using other types of export such as export to HTML and PDF while the fix is in progress.
Here is a JSFiddle example for illustration.
