[MAC OS] In-game cursor briefly stuck when edge panning with external monitor.

[ezewan]

I can't edge pan Dota 2 in-game with my external BenQ monitor. The mouse cursor will briefly stuck at the edge trying to move into another screen (lagged my game when this happens). It was okay until Mac OS Sierra. Please help to look into this. Many thanks!

Did you upgrade to macOS Sierra on the system? If so things were working properly and then stopped working properly with Sierra and that was all that changed?

[ezewan]

Yes, the problem happened after I upgraded to macOS Sierra. For now, that's the only thing that make the game unplayable via external display on this system.

You'll want to report this to Apple also, then.

this happens to me on El capitan 10.11.6, same specs mac

[TomNaessens]

Same here after upgrade to OSX Sierra.

[TomNaessens]

This seems fixed for me now. I can't recall it being in the patch notes neither from MacOS nor from Dota, so I don't know what has fixed it.

[gdrewb-valve]

I don't know of any changes to address this in Dota, but possibly something affected it. If ezewan reports it working also I'll close this out.

[TomNaessens]

I had issues with it today again, so it's not fixed (sorry). I have no idea what was different, but I'll try some things are report back when I found something.

[gdrewb-valve]

OK, thanks.

Hello, I am also experience this issue. This issue was brought up almost a year ago, so I was hoping there was some of fix (either on the user end or by a software update.) This behavior unfortunately makes the game completely unplayable unless I disconnect my second monitor and use the MacBook Pro's main display only.

Whichever edge of the screen touches the other monitor is the one that has trouble. As the original requester states: There is a brief moment (maybe 100ms or so) that the cursor actually jumps to be the other screen, while simultaneous lagging/stalling the game for an equal period of time. So long as the mouse is attempting to move off-screen, the game will be lagged out/stalled.

If played in windowed mode, the problem is worse and happens on all edges of the game window. Meaning, if the cursor touches any edge (top, bottom, left, or right) of the game window, the cursor will jump out of the window for a split second and freeze the game (sometimes almost indefinitely.)

The only work-around for this problem is to not use an external display, which makes me really sad because I'd like to not have to re-arrange my physical desktop every time I play DOTA2.

System Info: I have a mid-2015 MacBook Pro with OSX 10.13.1 (macOS High Sierra) that I play DOTA2 on with the graphic settings off/low. I recently added a second monitor (connected via HDMI) to get some extra viewing space, when I noticed this issue.

@dmaltsiniotis I use DisableMonitor in the meantime to be able to play on my external monitor while my internal monitor gets "shut off". I have no idea if it'll help you with desktop arrangement though.

[dmaltsiniotis]

Thanks @Silox,

DisableMonitor works great as a work-around in this case. I'll continue to use that tool and hope this issue gets some love in the future.

Cheers

[aalencar]

@dmaltsiniotis @Silox Did you guys find any real solution?

[dmaltsiniotis]

Hi @aalencar,

Unfortunately, there is no "real" solution to this problem, and it's a pain in the butt. I don't think there ever will be a fix either, because the attitude I have observed during my research has been: "it was working before the last macOS update, so there must be something wrong with the macOS, not our problem."

However, using @Silox's recommendation to install the DisableMonitor app seems to be an okay enough work-around for the time being. However, the app has crashed my mac a few times when switching between sleep modes, but it doesn't happen often enough to be a serious concern.

When I boot up steam, I just make a habit of turning off the built-in LCD using the app, and I'm at least able to get a session or two in. Then when I'm done I re-enable the LCD.

Thanks, -DM

[aalencar]

@dmaltsiniotis I also followed @Silox recommendation to use DisableMonitor, it doesn't work very well on my second monitor though. The only workaround I found was to set the display arrangement diagonally. It's not great, but at least I can play without much trouble.

If people experience this in other games too it must be an OS problem then. I will keep looking for some solution and keep you guys posted.

[mandal-ts]

There are 2 solution:

close the laptop lid use mirror mode on display setting

[OleksandrSechko]

still valid problem for any macos laptop with external monitor Any plans to fix it?

[xinan]

I'm still having this problem today, after many years.

[NickZorander]

I'm also having this problem with my m1 mac with Monterey 12.4 and external monitor

[pietro-rutzen]

Having same problem on my Mac, many ruined teamfights because of this

[MariusRossouw]

In the Terminal, execute

defaults write com.apple.dock workspaces-edge-delay 15 && killall Dock

will set the delay when dragging to screen edge to another desktop to too high that macOS would not do anything. Tried it myself and works for me.
