Safari tab images/titles going blank, first time seeing this bug

[mitchryan912]

It looks like this was an issue in Safafi 18.4 (LINK), but this is the first time I've ever seen this, after upgrading from macOS 13.7 --> 15.3.2 --> 15.4. It's always the 1 or 2 tabs next to the pinned tabs that do this.

I do have a LOT of tabs open, but that's not unusual for me. Oh, it looks like Safari 18.4 is also what's in macOS 15.4.

I'm having the same bug. Yeah, it's the latest macOS update that broke Safari

It appears to be a thing where once a tab gets to a certain size (from opening X number of tabs), those on the far left go blank.

It’s dependent on if the bookmarks on the left are showing or not. I can open 10 tabs before it goes blank with the bookmarks browser open, or 12 with it open.

I suspect that if my Safari window was narrower than the width of my 16” screen, it would be less. That also explains why I’m not seeing this on my Mac Studio, as I have 27” Thunderbolt Displays connected to it.

Happening on mine too. ugh. Guess what is at that location? You don't know until you hover over it.
