White Line on Left Edge of Gradient Rectangles in PDF Export

Hi,
I'm running into an issue when exporting my Looker Studio report to PDF. Thin white lines appear on the left side of small rectangles that have a gradient fill (dark purple to light purple). These lines do not appear in the web view — only in the exported PDF.

Important note:
Changing the fill to a solid color removes the white line completely, so it's clear the issue is specifically with how gradients are rendered during PDF export.

However, I would like to keep using gradients, so I'm looking for a solution that doesn't require switching to solid colors or converting shapes to images.

Has anyone encountered this or found a workaround?

Thanks in advance!

Below the examples of the issue :
In the top it how it look before exporting, and in the bottom it is in the pdf version with the white line
