Exclusive full screen does not work properly after Dueling fate updates

[bojunwu]

I'm using the 2017 15-inch Macbook Pro with Radeon 560 graphics card + i7-7820HQ and 16GB of RAM. For stability issue I'm using the lastest Mac OS Sierra, no high sierra yet. This is what I see when I launch the game today after the updates. Desktop-friendly full screen works but the resolution is so low on a retina display.

This is a FULL screen screenshot.

I have the same macbook and the same problem. I reinstall steam and dota but problem not leave. And also I don't have real full screen. If I move mouse to left top corner I have call Dshboard

[macbook15]

the same MacBook the same problem, that's too upset

[macbook15]

the screen resolution is 2880*1800,but only 1440 resolutions can be used properly, if use 2880 with a -fullscreen code, the mouse can't click the right side of the screen, it's disaster, the game has been ruined by the new patch.

[bojunwu]

As of Nov/2 the bug has not yet been fixed. Only part of the game is displayed on the screen.

Hey Valve any updates?

I have the same problem here. iMac 4k Please help!!!

@Oxidian2005 - what type of monitor are you using on your Mac Pro? we haven't yet been able to reproduce this on a variety of different machines but are trying to do so asap.

[webquali]

I have the same @jeffreythen problem on my macbook pro 15 2017

[Oxidian2005]

@natbro I use one 27’ Mac monitor. The thing is that even in exclusive full screen it is windowed and mac hot corners and dashboard still in use. Don’t think it has to do with actual resolution of size of the screen.

[bojunwu]

I have two 15-inch Macbook Pros. Both machines have discrete GPU. I only have this issue on the one with Mac OS sierra 10.12.6. The other one has high sierra 10.13.1 and it works just fine. But there is another issue with high sierra(GPU performance drop significantly after sleep) so I want to keep one of my laptop at sierra for now.

[webquali]

I have Hight Sierra and have really low fps 13

[bojunwu]

@webquali restart the machine solves the low fps issue for me. But it will come back everytime I put it in sleep mode. Guess it's an issue with high sierra.

[webquali]

@bojunwu the same problem

[Oxidian2005]

@bojunwu I had Sierra and updated to high sierra to see if it solved the problem. But fps still messed up and there isn’t exclusive full screen.

We are still having trouble getting a repro for this here. For those having the problem, can you please post:

• What is resolution of your desktop?
• What is the exact video setting you are using? (i.e. Exclusive Fullscreen - 2880x1800)?
• Steam -> Help -> System Information

Right now we don't have a repro. We'll need to get one to figure it out.

[bojunwu]

@danginsburg Thanks for the reply.

My desktop resolution is 2880x1800 Video settings are shown in the pic, in case the picture is not clear enough, the settings are: User Advanced Settings, Aspect Ratio 16:10, size 2048x1280(I tried to change this but it doesn't solve the problem),Display Mode Exclusive Fullscreen. Effects are most on and qualities are all high. Rendering quality is 100%.

Same issue please fix valve!!!!

[danginsburg]

Thanks, I was able to get this repro'd. It appears to be a regression in SDL which I am investigating. As a temporary workaround, you could replace ~/Application Support/Steam/steamapps/common/dota 2 beta/game/bin/osx64/libSDL2-2.0.0.dylib with the attached version.

We'll work on getting a real fix though.

libSDL2-2.0.0.dylib.tar.gz

[bojunwu]

@danginsburg Thank you. It's working. Will replacing this file affect future update of this game ?

[danginsburg]

@bojunwu If you Verify Game Cache it will replace it with the original version. It also will get replaced on a future update once we fix it. Hopefully we'll have a proper fix soon, I will update the bug when we do.

[bojunwu]

Thanks for the help. It works perfectly for me now.

[danginsburg]

The specific SDL commit that is causing the problem is this one:

http://hg.libsdl.org/SDL/rev/1e26564c7288

The problem is that after that change, CGDisplaySetDisplayMode fails in Cocoa_SetDisplayMode with kCGErrorFailure. The following is also output:

Nov 8 11:29:28 dota2[62909] : displaySetMode: unable to find mode dict in array

I'm working with SDL devs to try to find a fix. It is using an undocumented API (kCGDisplayShowDuplicateLowResolutionModes) to make it so CGDisplayCopyAllDisplayModes returns scaled modes, but then downsteam of that the CGDisplaySetDisplayMode seems to fail. It appears to be isolated to AMD, although I'm not sure why.

[danginsburg]

I've put in a fix for this, should be in the next Dota 2 Update.

[danginsburg]

The update has shipped. Should be fixed now.

Appreciate the fast response! Thanks a lot.
