Full screen streaming video (Amazon Prime, Youtube, Netflix) on Promotion resolution seems much smoother in my limited testing - before I would have to switch to a fixed refresh rate to prevent micro stutters.

Edit: MBP M5 base model

A long-standing bug in HDMI EDID synchronization on MacBook introduced with Ventura has been fixed. I had filed a Feedback, and was just contacted by an engineer to test with the latest version.
My Samsung Odyssey G75F now works perfectly over HDMI!

No issues on my M4 Pro Mac mini until now.

I already planned downgrading to Sequoia months ago because of permanently overheating while doing nothing and way too much memory usage.
With every new (beta) update anything got worse for me but that changed somehow since 26.3 Beta 2 or 3. Seems I'll stay for now, although I still hate that ugly rounded more space-taking window design. But I use many open source apps anyway that don't adapt the new design.

Edit: Seems even the short flickering with colored lines when waking up my non-Apple display is gone. I saw it once today again. Shortly after everything is on the screen, for about a second there is a block of vertical lines in several colors and length on the left side of my screen. At least it's not every time anymore and also never really mattered.

There is no mdworker crash when rebooting anymore.

I do have still some Finder problems like a missing sidebar or something hiding behind the sidebar, both after a logout or reboot. It doesn't remember my latest setting completely since 26.2.
At least the high CPU usage is gone since I installed XtraFinder, what doesn't even support Tahoe officially and seems to make less problems than in Sequoia. At least I didn't experience any since I installed it in 26.3 Beta 2 I think. In Sequoia I uninstalled it several times because of several issues or crashes.

What happened to those strange Music app graphics glitches in the RC? Was it Intel only? I don't have a music library or Apple Music at the moment and also no Intel Mac.

Wow, I must try this out.
My M4 MacBook always had trouble to connect to the NEC overhead projectors in our university. I had endless support calls about this and even got the mainboard switched - only to be forced to fall back to a certain USB-HDMI dongle from Anker, as it was the only one that worked reliably...
Nobody mentioned to me that this actually might be a software bug in macOS 🙁
 
There appears to be a new issue since I updated to 26.3 across the board yesterday evening.

I have a medicines reminder set for 08:00 every morning. At least since 26.2 was released, I could clear the alert on my watch or phone and, within a few seconds, I could see the alert on macOS clear.

This morning, I acted on the alert and recorded medicines on my watch, and the alert disappeared on iPadOS and iOS and, naturally, on my watch. But it has remained visible on macOS. I've used iPhone Mirroring - disconnecting and reconnecting several times.

Just checked Bluetooth on my phone - it is on, and, as always, checks for other local devices - says whilst it can see my MBP, it cannot connect to it as it is not supported. But the alert has now disappeared.

Do I have to positively connect my phone to my MBP with Bluetooth despite it saying not supported in order for alert clearing to work?

I know exactly what you are talking about. I also have a medications alert that fires in the morning. Everything still worked smoothly for today, I logged meds on my watch and the alert did disappear from my Mac ....... but while my other devices are 26.3, I am not on Tahoe yet, it was Sequoia 15.7.4 on my Mac (which also just released yesterday).

I do not think that you would need to set up additional connectivity for alert clearing. If the phone can send the alert to your Mac, it can also send the alert clear message to your Mac. This was either a fluke or a new bug, check and see what happens next time. (And maybe reboot everything in between now and then just to be sure.)

You don't have to connect your phone or watch to your mac with bluetooth. The connection should work seemlessly through iCloud. As long as each device is connected to the internet and all devices use iCloud to sync data, it should work.

Emphasis on "should." I have not experienced this exact issue you describe, but I've experienced other issues where a change on one of my devices SHOULD be reflected on all of my other iCloud-connected devices, but does not.

It's frustrating. But usually, in my experience, it starts working after a while.

Good luck.

It looks like System Settings Spotlight settings problem has fixed itself with this release (was present in RC).
 
Still buggy.....

Menu bar problem is NOT fixed. Still doesn't show up most of the time, making Tahoe worthless to use. This has been happening all through the 26.3 fiasco.

Also, Firefox continually hangs

So it's still buggy (I am on RC ending in 125, and I think that's the very latest).

I sure hope Apple finally fixes this.

What is the exact problem?

My only menu bar problem is Proton VPN since a longer time.

Sometimes it randomly doesn't show the menus when I open the full app, even the Apple menu is gone then. But I also install beta versions of that app, not sure if it's only in those. Never happened in any other app. At the moment it seems to work fine.

If it's not working all of this is empty:
