Description Omar Purata Funes 2024-05-26 00:58:49 CEST

Description of problem:

Hello Mageia developers. Thanks for taking the time to read this bug. Currently, the shipped GNOME version in Mageia 9 is 44, and it uses wayland by default. This makes the provided Emacs package behave strangely inside a wayland session, mainly due to graphical bugs such as black corners/borders when snapping the GTK window.

I know the v9 errata proposes switching back to Xorg. However, I think that may be overkill for this package.


Version-Release number of selected component (if applicable): 28.2


How reproducible: Probably easy

Steps to Reproduce:
1. Install emacs via dnf
2. Open a new emacs (gtk) window and snap it to either side of the screen.
3. Notice the errors in the borders of the window.

I tested this with both stock adwaita and third party themes, and the issue still persists. I managed to compile emacs for myself using podman and the --with-pgtk configuration flag, which seems to enhance support for wayland. However, I did not know how to “repackage” the Mageia version in a suitable .rpm format.

I also marked this as minor since, “technically” all I had to do was steal the configuration used in mageia emacs and add the --with-pgtk flag to configure.

Thank you for the report. Agreed, it is not serious.

Assigning this to ns80, the main maintainer of emacs.
If you (Nicolas) can put a version of emacs in Core/Updates_Testing compiled as the user suggests, so that *he* can try it from there, that would be easiest for him.
Otherwise, explain whether & how he can convert his compiled emacs into a package so that he can install it locally to try. I suspect that might be complicated.

I'm willing to help with testing if my assistance is needed. The mageia podman image has proven to be very useful for these tasks.

I made some research and tried with both fedpkg-minimal and rpmbuild to no avail. I'll keep you updated if I find anything else in the meantime.

Thanks for taking this into account!

Hi,

For Mageia 9, emacs cannot be built with --with-pgtk flag because:
1) It means emacs could not be used with x11 any more but only with wayland.
2) That flag is in emacs >= 29 and Mageia 9 ships version 28.2.

For Cauldron, I will try to build emacs twice when I have some time.

Best regards,

Nico.

Hi,

For Cauldron, could you test if replacing emacs-29.3-3.mga10 by emacs-pgtk-29.3-3.mga10 solves the issue, please?

Best regards,

Nico.

Comment 5 Omar Purata Funes 2024-06-01 22:46:35 CEST

Sorry for the late response. I had to test the package to give proper answers. Redirecting display output from podman to wayland was a complete odyssey. 

I tried both:

- emacs-pgtk-29.3-3.mga10.x86_64 inside Mageia Cauldron container image
- emacs-pgtk-29.3-3.mga10.x86_64 inside Mageia Cauldron qemu

I tried backporting it using Mageia 9 libraries but I think this is not possibile due to incomatibilities with: libc (version), libjansson-devel (couldn't find that in dnf) and emacs-common.

Thanks a lot for attending this.

Hi,

I built emacs 29.4 for Mageia 9. Can you test it, please?

Best regards,

Nico.
