Re: [gtk-osx-users] Black screen on ARM based Macs

Miroslav,

I built a fresh meta-gtk-osx-gtk3 with macOS version min set to 10.12, symlinked $PREFIX/inst to 
$PREFIX/Resources and copied notecore-bin to $PREFIX/MacOS/notecore so that it would find my libraries with 
@executable_path/../Resources, then ran notecore from a jhbuild shell. It displayed correctly on both Retina 
and not. That tells me that whatever is messed up it isn't Gtk.

There seems to be a lot of extraneous stuff in your bundle as well, your launcher-script looks rather 
haphazardly ported from a Gtk2 one, and libspell is in the wrong place.  So start off with a fresh build of 
meta-gtk-osx-gtk3 in an empty folder starting with bootstrap-gtk-osx and for safety libspell too. While the 
build is going on clean up your bundle file so that only the libraries and other folders that you need are 
installed and redo your launcher script based on gtk-mac-bundler/examples/gtk3-launcher.sh.

Some other things that need addressing: You seem not to have updated your use of gtk-mac-integration for 
Gtk3: It doesn't work, the menu bar is on the window instead of at the top of the screen. The Gtk-supplied 
icons aren't visible, perhaps you're trying to use the GTK_STOCK icons that were deprecated in Gtk-3.0.0 and 
removed somewhere around Gtk 3.10. I thought at first you'd gotten tripped up with the removal of the 
deprecated stock names in Adwaita-42, but they don't work with Adwaita-3.38 either.

Once you've got a clean bundle I'll test it for you, but you might want to get the Additional Tools for Xcode 
13 from https://developer.apple.com/downloads. It includes Quartz Debug that might enable you to fake retina 
resolution if your MBA has enough GPU to support it.

John Ralls

Miroslav,

Thanks. I can confirm that it’s a Retina issue, not an Apple Silicon one. I have the same 1/4 render on my 
Retina monitor on both my Intel Mac Pro and my M1 mini. It looks normal on the non-Retina monitor on both 
systems.
Next I tried my 2014 MBP Retina running macOS 11 BigSur. Same problem. Maybe this is your user’s first 
experience with Retina displays? 

I hadn’t really paid attention to https://gitlab.gnome.org/GNOME/gtk/-/issues/4342#note_1299321 until now. 
I think that’s a separate issue from the Monterey absolute value change that screwed up flipping the 
coordinate system. His issue appears similar to yours and he worked around it by removing the scaling 
line,https://gitlab.gnome.org/GNOME/gtk/-/blob/3.24.33/gdk/quartz/gdkwindow-quartz.c#L194 , altogether. I’m 
not sure why that would be necessary for you and him and not for anybody else. That line has been there for 
6 years, having been introduced in 
https://gitlab.gnome.org/GNOME/gtk/-/commit/3f077ec36f4a59e803c9f4509996269c862e04af. Note that the scale 
division in the CTM is countered by scaling the size of the Cairo surface at 
https://gitlab.gnome.org/GNOME/gtk/-/blob/3.24.33/gdk/quartz/gdkwindow-quartz.c#L352.

Hi John,

you can find the installer with new build here:

Thanks for the help.

Best regards,

Miroslav,

I installed NoteCasePro from your download page to my M1Pro MBP running the Ventura developer beta and it 
looks just like your screenshot. It also has Gtk-3.24.30. Can you give me a link to your Gtk3.24.33 
installer?

I think that the reason you can't see the problem is that your 2017 MBA doesn't have a Retina display. 
I'll check it on my MacPro that does have a Retina display in a bit and follow up.

I haven't tried cross-compiling to arm64 from intel yet, but it didn't work at all back in the PPC->Intel 
days so when I was distributing PPC apps I built on the respective machines. Universal builds definitely 
don't work from the command line, I did try that. I can also say that I haven't seen any significant 
behavior differences between running Intel builds with Rosetta2 and native builds on M1s, so I think it's 
unlikely that that's the problem. The Xcode version shouldn't matter either.

Regards,
John Ralls

Thanks John,

I don't have M1 hardware, so I depend on users to help troubleshooting the issue. 

I do my build on Intel hardware (macOS 12.0.1, MacBook Air 2017, XCode 13.2.1), with the following target 
setup:
setup_sdk(target="10.9", sdk_version="native", architectures=["x86_64"])
i.e. program is being run on M1 through Rosetta.

The issue was reported against the build using GTK 3.24.30, then I've rebuilt the program to use latest 
v3.24.33,
but both users reported that the issue was not fixed (screenshots below). They are not developers, so 
they did not try running gtk-demo.

I do have an app log that redirects all GTK logging, but could not find any clue (GTK error/warning) in 
it. The same binary works fine
on Intel hardware, no such issues were reported.
I will re-check to make sure they properly installed the newer build.

Could adding native "arm64" architecture into the setup help with this bug (based on the bug that was 
fixed)?
Do I need to use newer XCode for this?

Best regards,
 Miroslav

Hi,

several users of my program reported the main application screen being partially black on ARM based Macs 
(M1) on macOS Monterey.
Digging online, it seems that this bug has been known:
https://gitlab.gnome.org/GNOME/gtk/-/issues/4342
https://gitlab.gnome.org/GNOME/gtk/-/issues/4395

I've rebuilt latest gtk-osx yesterday (moduleset-stable), but the issue still seems to be here.
What's the status of this issue in gtk-osx?


Miroslav,

The fix for issue 4342 is in Gtk+-3.0 since 3.24.31 and modulesets-stable has 3.24.33, so perhaps the 
problem your users have found isn't the same one. 

Is this an Apple Silicon build or an Intel one? What minimum macOS version did you specify? Does the 
problem reproduce in gtk3-demo or is it just your app?

Regards,
John Ralls
