Just FYI, I never had any of these issues with Lion. Sorry if I haven't explained things very well, I hope it makes sense.Ĭould this be a specific issue with this particular model of MPB, this program and Mountain Lion? If I uninstall the program or prevent it from booting at startup and then repeat the above process the blue screen tint problem disappears, I've up to now been unable to reproduce this issue unless this program is running. If I close gfxCardStatus without rebooting the computer the problem can be reproduced each and every time. If I manually switch back to the Intel GPU or allow it to switch back by itself by closing all apps, the blue tint disappears.
GFXCARDSTATUS 2.1 PRO
I installed Mountain Lion on my Macbook Pro this afternoon and have discovered an issue with gfxCardStatus.īasically while the gfxCardStatus is running and the nVidia GPU activates through any program that requests it, the whole screen changes to an odd blue colour cast, the only way to describe it is like as if a wrong colour profile has been installed. I would fix this myself but I am unable to get the current release to build(see other ticket). However what is happening now is really unusable as integrated-only mode often causes the entire machine to be switched to discrete-only mode permanently rather then just briefly on exit. Yes its true that this would not be true 100% integrated-only, as some apps would briefly switch to discrete mode on exit. Ideally, gfxCardStatus would also detect when it goes back to integrated, and then switch the dynamic-switching flag back off again when the user is hoping for integrated-only functionality. This is very undesirable and makes integrated-only mode unusable.Ī proper fix for this logic error should be to detect that when an app forces to discrete mode on exit while in integrated-only mode, the dynamic switching flag should be temporarily turned on, so that dynamic switching can switch back to integrated mode as soon as possible. When an app forces to discrete mode on exit, the dynamic switching flag is left unchanged (OFF) and the user returns to OSX permanently in discrete-only mode, rather then integrated-only mode. Having that flag off applies to both integrated-only mode and discrete-only mode. This mode is tracked internally by setting the Dynamic-switching flag to off. The problem is that when the gfxCardStatus is trying to use “integrated-only” mode. If gfxCardSatus is set to dynamic switching, this is no problem, it will subsequently switch back to integrated mode as soon as the app is completely exited.
Some apps when they quit are switching to discrete graphics as they quit.
