Strange screen resolution and crash on macOS Big Sur

[warnes]

I am also seeing this using radioconda. Homebrew doesn't have this issue.

I forgot to mention: I'm seeing the resolution issue, not the segfault.

Just tagging possibly-related issues for tracking:

Non-merged workaround for high DPI displays with macOS: gnuradio/gnuradio#4814
Various issues with GR on arm64 macOS: gnuradio/gnuradio#4420

[ryanvolz]

Closing until I hear that this is still an issue.

[ryanvolz]

I think I've heard of this being a problem for GNU Radio itself (not just radioconda) with retina displays on macOS (hence the 1/4 screen, it doesn't get scaled properly for the high resolution). Searching the GNU Radio github though, I don't see it as an existing issue, so I probably just heard it through the grapevine. I'm going to suggest posting this issue over there to spur upstream to try to fix it.

That's a useful data point, thanks! Homebrew doesn't appear to have any extra patches for GNU Radio, so I'm wondering what the difference is. Probably something lower in the gtk3 graphics stack. I'll do some more digging.

@warnes Can you tell me what version of pygobject and gobject-introspection the working Homebrew build uses?

@warnes Check out my proposed fix in gnuradio/gnuradio#4814 (comment).

[ryanvolz]

I have patched packages ready to go here and here. If I can get confirmation that the change in gnuradio/gnuradio#4814 (comment) works, then I'll merge those PRs and make a new radioconda release to fix this.

https://github.com/conda-forge/gnuradio-feedstock/pull/85/files worked as a fix for me in conda. I just had to reinstall gnuradio 3.8 using conda. Thanks for the fix, @ryanvolz!

@ryanvolz
I manually applied your patch to a pure brew installation of gnuradio 3.9.3.0 , which originally caused the resolution problem. Now it works perfectly. Many thanks!

[ryanvolz]

Crash possibly fixed by this update to cairo?

[ryanvolz]

Any chance gnuradio/gnuradio#6352 fixes this? That's a python-only fix, so you can manually edit the appropriate installed python files to test it.
