Mac mini M4 pro
I leave the Mac until screen saver comes up. Then I stop the screen saver and the dock is hidden.
It's not only hidden but refusing to come up properly. Then I have to go to System settings->Desktop & Dock to switch on&off "Automatically hide and show the Dock".
This keeps happening and only started after the OS upgrade.
Mac mini (M4)
Have seen this issue before and they too were using macOS 26.0 with a Mac Mini
They may have said that using the Terminal command may have fixed the issue
killall Dock
Personally, using both a M2 and M4 Mac Mini with Tahoe 26.0
Have yet to experience this Dock issue
If all else fails
Holding the Option key
Finder >> Go >> Library >> Preferences
Find the .plist file >> com.apple.dock.plist <<
Move it to a place for safe keeping as you may or may not to put it back
Drag to com.apple.dock.plist out of its location
Restart the computer and then Test of the Dock issue persists or not
In theory the restart should create a new .plist file for the Dock
If no issues , it may indicate the original files became corrupted
I am also having this issue, M3 24inch desktop.
I have Automatically Hide and Show the Dock set to OFF. And had it set to off before I updated to Tahoe. It is still set to OFF. But every now and then I find the dock hidden. Seems random, or at least I can't tie it to anything that might be triggering it to hide. It will be fine for days - always showing, and then randomly I will notice its hidden and I have to right click it and choose "turn hiding off"

Random time my dock turns on auto hide after screensaver or sleep.
MacBook is dock closed & connected to my Studio Display.
Bottom line? You’re just going to have to wait for Apple to get around to fixing it if it is a bug. Apparently most users are not seeing this. If it were universal these forums would be overwhelmed with posts like yours. In my own case the issue disappeared after a week of using Tahoe and has not come back so far.

There its no software fix or magic wand to fix this. We simply have to wait for it to be dealt with in some future update. And as bugs go this a is a very minor one that’s mostly cosmetic. Apple software engineers have bigger fish to fry I’m sure.
All I had to do was toggle the System Settings->Desktop & Dock->Automatically hide and show the Dock->on/off/on/off and the problem went away.
I have system settings constantly on dock. So when it happens I just click on-off and it is OK till next time
Here is some more information.
I have two monitors connected to the Mac mini via HDMI and USB-C to DP.
The DP monitor is the main display while the other monitor is shared with a MacBook Pro.
This issue has been happening on the main display (DP) while I have the extended monitor set to USB-C for the MacBook Pro.
That seems to be a running theme with Tahoe so far. No Spotlight results? Kill the process and it’s fine thereafter. Space bar not playing/pausing in the main Music window? Show then hide the playing next panel and it works normally thereafter. Etc.

The dock problem is still happening since the update 26.0.1. This update obviously didn't fix the bug!
Correct, the release notes for Tahoe 26.0.1 mentioned NOTHING about this issue and therefore nothing has changed. Like all software developers bugs are prioritized according to impact. While this bug is annoying it is not a showstopper. Just wait.
26.0.1 did not fix. If apple believes it's a 3rd party app, I only have a few. Brave browser, tonex and hx edit. That is it. The dock hides just about everytime after shifting tiles screen saver. Very annoying.
26.0.1 did not fix it because that bug is not on the list of things to fix yet. While mildly annoying this bug is not a show stopper in any way. Software engineers have bigger fish to fry. No need to obsess over it. It will be dealt with eventually.
For me it was just the opposite, I had set my screen (as always) to go black when not in use and recently I started having this problem so I disabled this and configured a screen saver and the problem still continues.
Having the same issue on an M4 iMac. Will try some of the fixes here and report back.
I tried doing the toggle before deleting the .plist preferences, but I may have just done on/off, not on/off/on/off
I have the same problem on my 2 Macs. annoying! Have to switch on and off the automatically hide dock.
Dock keeps auto-hiding on macOS Tahoe
