Hi there, Thank you for contacting pdf.js express forums, I tested the pdf.js demo site [PDF.js Viewer Demo | PDF.js Express](https://pdfjs.express/demo) on BrowserStack and was unable to reproduce: Windows 10, Edge 107 (latest): ![image](https://canada1.discourse-cdn.com/flex031/uploads/pdfjscommunity/original/2X/d/d93bef11b1cdb9527687c35d39b2d221a8a8a6e1.jpeg) Windows 10 Chrome 107 (latest): ![image](https://canada1.discourse-cdn.com/flex031/uploads/pdfjscommunity/original/2X/d/d442badfc3422cba9a0a8eb432af661283e2f091.jpeg) Note that the demo site is on 8.7 Can you try upgrading to the latest pdf.js express version and see if you can reproduce the issue? Otherwise can you send the pdf file that is having the issues? Thank you in advance.

Thanks @tgordon. Note this is also happening on windows 11. Are there any plans/possible to address this issue? I.e. is it even possible for PDFJS to address this issue with chrome? Thanks. ---

Hello fuse, Unfortunately this is an issue with Chrome/Windows and the graphics drivers. You could possibly try recalculating the layout of the document to trigger a re-render: [recalculateLayout(pagesToRecalculate)](https://pdfjs.express/api/Core.DocumentViewer.html#recalculateLayout__anchor) Best regards, Tyler Gordon Web Development Support Engineer PDFTron ---

Hey Tyler, I just wanted to see if there was any change in the position of this? Do you know of any other customers who have had success using recalculateLayout which resolved this problem? Thanks. ---

Hi Fuse, Unfortunately our investigation into this issue is ongoing. We have had other customers try willReadFrequently: true on the iframe returned from pagesRendered but they have been hit-or-miss Best regards, Tyler Gordon
