Some parts of the rendered text seems to be shifted

Since using Sonoma I have this strange text rendering issue that crawls in at unspecific times / pages, so no apparent cause. This happens in Production Safari but also in the Safari Technology Preview.

Thank you for the report. Could you please add more details, especially your hardware model, and the latest OS version you've seen this with?

Safari Rendering issue

see the Screen Recording: Even after page refresh some parts of font renderings get distorted again. This is a fresh install of macOS Sequoia, btw - bo plugins or other sw running.

Thank you for these details. This appears to be the kind of issue I'd expect to see with unsupported hardware, I don't think that we've seen reports of such with devices that are supported by macOS Sonoma or Sequoia.

This seems like something for OCLP developers to look into, and not an issue in WebKit.

Dear Alexey,
I also suspected already that it is unsupported as I am using OCLP on unsupported he.

Do you have any pointer what could cause this? It also happens in Mail (ok also WebKit based), but also PDF Preview.
Thank you,
Joachim
