We have a custom report where the text in the fields with a lot of text overflow or overlap when exporting the report to a PPTX format. The report looks ok from the UI or when exported to a PPT format; this only occurs when exporting to a PPTX file format.
We just upgrade to Aspose.Slides for SSRS version 4.8.0. This issue was occuring in version 4.3 and now in version 4.8.0. Attached is the rdl file.
