Did I do something wrong?

I have been playing around with obsidian for quite a while now (only trying out plugins and writing some css overriding the stylesheet of the minimal theme.

A view months ago I noticed some issues being displayed in the developer console.
I googled but I havent found any relevant information on whats causing them. Did I do something terribly wrong?
Can I fix it? Do I need to fix it?

These are the issues I see

• Page layout may be unexpected due to Quirks Mode (415)
• SharedArrayBuffer usage is restricted to cross-origin isolated sites
• Deprecated Feature Used - SharedArrayBuffer will require cross-origin isolation. affected resource: app.js:1

The issues are too technical for my understanding, most of it flies over my head. Some of it reads as if obsidian itself has issues due to changes within the chrome / electron ecosphere, something that the obsidian dev team is handeling, but I have no expertise in that matter and am happy if somebody can enlighten me.

Besides these issue-notifications I do not experience any problems with obsidian - everything runs smooth and beautiful.

What version of Obsidian? What installer version? If an older installer, try downloading and reinstalling.

Have you updated your community plugins and themes? Perhaps you’re using older versions that are causing some warnings.

(Otherwise I don’t know. I can’t even make the issues tab open for some reason, so I can’t check if I have similar messages.)

My Obsidian version was 1.6.3 (Installer 1.4.13).

I just updated the installer version, the issues still persist.
Everything else is up to date… Could it be my own css snippets?
