Hi Pablo,
I am on Windows 10 and using Firefox 119 with default PDF.js.

I made a completely new profile to check and the issue exists there too.

Though after testing a bit I realized that the white lines appear on specific zoom levels and disappear on others.

White lines appear on sumatra too but on a specific zoom level.

There are now some bottom white lines too on some zoom levels.

Okay the issue seems to be happening on all pdf files regardless of whether it was made from context or not. The black background just allows me to notice it.

Thank you for checking.

Hi Mia,

opening your attachment with Firefox 119 (and the version of PDF.js that
comes with it) on Linux, I was not able to find any white line in your
attachment or in the output from the you source (with zoom set to 400%).

Just in case it might help,

Pablo
