Desktop App lagging whenever there is a PDF Viewer rendered

What’s happening

Whenever I have a file with a rendered PDF viewer (the builtin one) the entire page just laggs and freezes sometimes. It is completely stuttering only showing what I have typed every few seconds. It’s like the screen in only refreshing every second or so. The actions I do (type/click) are all performed completely fine but I can only see it visually after some time and all at once.
When I switch the tab or scroll far down on the same tab the lag goes away (When the PDF Viewer is out of sight).

Things I have tried/tested

  • Tested if it’s the PDF (trying to view it in a seperate window, with another app, with Mozillas PDF viewer)
  • turning off CSS snippets
  • Disabling all Themes
  • Turning on Restricted Mode
  • Removing the PDF from the file (the lag went away but that’s not resolving the issue. I still want my PDFs. It’s only to prove that it’s actually the Viewer that caused the issue=

I’m having this problem as well after the latest update. This problem persists in both the Linux (Ubuntu) version and the Windows version. I tried all the things you mentioned, changed to the default theme, disabled all plugins and snippets. So it seems to be the native PDF-rendering…

Chiming in to add that I am having Obsidian 1.7.7 lag/freeze when PDFs are rendered on MacOS (Sequoia 15.1.1) as well.
