BST Safari stops responding to cursor keys and window stops snapping/resizing

I don't think this is a BST bug as such, but it is breaking BST functionality when it occurs. This only started happening in the last couple of weeks.

It happens when Safari has been running for some time, I haven't pinned down an exact time, it can certainly happen within an hour of use.

What happens is that Safari stops responding to cursor keys in a normal way. Pressing the up arrow for example just takes you to the top of the page and pressing down doesn't move the page. At the same time the snapping for BST, for Safari breaks in the following ways:

  • snaps no long snap, instead the Safari window slides from one snap position to another
  • snapping to say half the screen with a keystroke doesn't work, it cycles through previous window sizes instead
  • snapping to another monitor with a keystroke doesn't work, again the window just cycles sizes
  • dragging a window to a snap area moves it to that side of the screen, but does not resize the window to fit the area

Closing Safari and reopening fixes the issue, for a while, until it happens again. It happens in the latest Safari Technology Preview release as well.

It is only Safari and BST that seem to be involved. The only significant change I made around the time it started was moving to the new 1Password 8 release, I can't think of any other interesting software I installed since.

I use ctrl-opt-cmd-left/ctrl-opt-cmd-right/ctrl-opt-cmd-down for my most command BST actions.

  • MacBook Pro M1 Max
  • macOS 12.3.1
  • Safari 15.4
  • BST 1.9.5

it’s 1password 8. So far I thought this only affects Chrome based browsers, but maybe also Safari? Have a look here for something that might help with the window snapping: Latest Chrome stable doesn't work with Better Snap Tool - #29 by Andreas_Hegenberg

I was wondering, but hadn't quite brought myself to uninstall it.

I'll give that defaults value a go and report back.

Sure enough the BSTEnableEnhancementCheck instantly made BST work, even though my Safari instance is currently in the broken state. The cursor keys still don't work within Safari of course, so I guess I'll be trawling the 1Password forums next...

I wonder if disabling 1Password's access to Accessibility stuff would be work around in the meantime ?

Thanks for such a rapid response.

Ah, now I know it is 1P8 causing it, I can reproduce it at will:

  • launch Safari
  • cursor keys work to scroll the page
  • summon 1P8 with cmd-\
  • cursor keys no longer work to scroll the Safari page
  • close/relaunch Safari
  • cursor keys work to scroll the page

So the reason the timing felt random, is that it was only happening the first time I summoned 1P8 after each relaunch of Safari.

Curiously though, I've not seen the same issues with BST + Chrome + 1Password 8. I use both Chrome and Safari all day equally and the issue has never occurred on Chrome.

disabling 1password accessibility would work but would prevent some advanced 1password features from working. I guess the 1password team didn’t know about the issues caused by enabling the enhanced user interface modes for various apps…

I wonder whether they will find a workaround, because I don’t know of any for their usecase. Maybe they could switch to only temporarily enabling the enhanced mode. (Like BST, which disables that mode temporarily before each snap if you have run the terminal command)

With my current setup disabling the access to accessibility for 1P completely disables the auto fill in features in the browsers. This is because I'm relying on their new "universal auto fill" that doesn't require you to have the relative clunky browser extension installed.

They have said they are actively investigating it. I would hope they could work round it, as I think they have to only briefly interact with Safari:

  • cmd-\ triggers auto fill
  • you select the credentials to fill (in their popup)
  • it fills in the credentials

So I'd hope they'd only need to enable enhanced mode while they grab the website details and do the filling.

But as a developer myself, I know things are not always that simple.

I am curious to know whether this is an issue that only impacts some users, or whether they just didn't notice it was breaking cursor key navigation.

We'll see...

it affects many users through various apps, I have also seen the cursor issue in e.g. Microsoft Teams. For BST i’ll push an update that automatically enables the setting from the terminal command later this week.
