Big Picture mode crashes on game exit

[Sparsity]

Hi,

I have recently started using Big Picture mode again and I find that it often crashes when exiting a game (and sometimes when switching from regular windowed mode). Since I was using the beta client, I asked in the relevant forum, but it also happens to me with the current stable build (Nov 26 2018, at 12:25:41). Since it has been a long time since I last used it, I don't know if the upgrade to Mojave (I am currently on macOS 10.14.2) had anything to do with it.

Is this an issue to others, or can someone suggest ways to diagnose what might be happening?

Thanks.

What does youe crash log from Console app state? Copy and paste it here for annalysis

Console.app's system.log entry show the following when the crash occurs when exiting a game:

Dec 13 16:26:04 Silverplane steam_osx[3191]: steam_osx(3191,0x10cf915c0) malloc: Incorrect checksum for freed object 0x7fb70534d048: probably modified after being freed.
	Corrupt value: 0x0

If there are other Steam-related outputs accessible from Console, I don't know where to find them.

Opening System Preferences, entering Energy Saver and unchecking the “Automatic graphics switching” option seems to prevent the crashes.

Hmm, I'm having the same problem where Steam Client crashes on game exits while in big picture, and sometimes on mode switches out of big picture. But I don't have an "automatic graphics switching" option in my Mojave preferences.

@semt3x! I have preferred my overall computing experience more since switching to Mac for primary use, but I do understand that gaming on Mac is largely an afterthought. That said, as long as Steam keeps taking my money in exchange for games, I'll keep looking for progress to be made to improve the experience.

Controller support is also unnecessarily dodgy ... I've got an xbone-s controller that hooks up to the computer via bluetooth no problem, and is recognized by the steam client, no problem, but in between the steam client and the individual games, it's a real crapshoot what voodoo I'll have to perform before I can actually play the game with the controller.

When I noted here that the problem seemed to be related to graphics switching, I wrote to the support team and after an exchange of messages I was told that the problem had been identified and that it would be eventually fixed. I have been playing for some time without using a controller, but now that I have tried it, the problem seems to still be there.

Also note that I think that before losing my focus on the issue I managed to trigger the Big Picture Mode crash without the automatics graphics switching enabled, so perhaps it is more of a mitigation strategy than a solution. (As for the dodgy controller support and other bothers of playing games on macOS, I agree.)

This is happening to me too, MacOS Mojave on a 2017 Air. Switch Pro controller over Bluetooth in Big Picture Mode. Quitting a game (via in-game Quit or Big Picture overlay) quits the game _and_ Big Picture. Steam Cloud fails to sync on these exits.

That solution SOLVED the problem for me :
