914280 - Disappearing cursor on Mac Nightly

Status: RESOLVED WORKSFORME

(Core :: Widget: Cocoa, defect)

Description

[Richard Newman [:rnewman]]

Figured I'd file this, even though I have zero info for it.

Current Mac 10.8, current Nightly.

Switch away from Nightly with Cmd-Tab. Switch back. Cursor is now invisible (hover still fires, click works, just invisible *for the entire OS*).

Switch to another app and it comes back. Mouse over the dock and it comes back. Sometimes a page load will make it come back.

Nothing in any console.

Is this still an issue ?

Comment 2

It still happens veeeery infrequently.

Curiously, I see this very frequently with Thunderbird (Beta). Occurs in the middle of using it.

Pure speculation, but I wonder if bug 411273 might have somehow caused it. The only cursor changes Thunderbird does are for changing to the hand-icon on links, and showing the busy state when network stuff is happening. We got rid of a lot of the busy-pointer stuff long ago in Firefox because it made things feel janky, but TB still uses it extensively. (Some websites, notably Facebook, still set this cursor state.)

Mac OS X itself has longstanding intermittent issues with the cursor not changing shape when it should.  So does (or perhaps did) Firefox when moving the mouse outside of a plugin.  It's possible to programmatically make the cursor disappear.

There's no point in speculating here until/unless we get good STR for some particular case of this problem.

Hmm, I see this too quite a bit on Daily. I can't say I've noticed it until a few weeks ago, so it seems it's gotten worse.

Unfortunately I still can't figure out the trigger. I will however try to nail it down in the future.

It seems the issue still persists on Firefox 45.0.1 OS X El Capitan.
