hildon-desktop doesn't render correctly

I'm trying to run hildon-desktop on lima driver. Before it hung early on, anarsoul suggested that I try again, and this time it renders the initial screen. I've made an apitrace, like so:

DISPLAY=:0 CLUTTER_BACKEND=x11 HD_NOTHREADS=yes CLUTTER_DRIVER=gles2 apitrace trace -o hildon-desktop-apitrace.log -a egl /usr/bin/hildon-desktop.launch

Output trace file is here: https://wizzup.org/hildon-desktop-apitrace.log

I build mesa from commit 096a0d05 ; and the kernel tree is here https://github.com/maemo-leste/lime2-linux/tree/lime2-and-twister-4.19-rc4 (it's basically linux@15b43d77 plus some allwinner patches for spi screens)

I hope the apitrace is useful, please let me know if I need to generate it differently. hildon-desktop is also available from this debian repo, for armel, armhf, aarch64 and amd64: https://maedevu.maemo.org/leste/

Here is another trace from my n900 (armhf, powervr driver): https://wizzup.org/hildon-desktop-apitrace-n900.log

This at least replays on my i965, as opposed to my previous log.

apitrace not being happy with my previous traces turned out to be an apitrace issue: https://github.com/apitrace/apitrace/issues/599

I have now made a new trace (with the unpack_subimage extension disabled) that replays properly on i965, like so: DISPLAY=:0 CLUTTER_BACKEND=x11 HD_NOTHREADS=yes MESA_EXTENSION_OVERRIDE=-GL_EXT_unpack_subimage CLUTTER_DRIVER=gles2 apitrace trace -o hildon-desktop-apitrace-nounpack-subimage.log -a egl /usr/bin/hildon-desktop.launch

It can be found here: https://wizzup.org/hildon-desktop-apitrace-nounpack-subimage.log

It renders quirky/weird on lima, some background is shown, but none of the actual 'moving around workspaces' ever happens, nor is the application menu visible.

changed the description

I checked out cea7264d and from a brief test things have improved quite a bit! hildon-desktop renders the workspaces correctly now, the application menu launcher also seems to work, I can also switch windows and most of the times it seems to render correctly. The application overview/expose doesn't seem to render window titles yet, but otherwise: great work so far. (And: thank you!)

Thanks, good to know your feedback. I'm working on generic X11 support, hope will benefit your application.

Maybe you need this patch for flicker problem on sunxi platform:

https://github.com/freedesktop/drm-misc/commit/7b24eec754ba0f0f794ab09413dcde2585b4a84b

Thanks, I have applied it. I didn't see much flickering on A33 tablet (btw, here is a video: https://www.youtube.com/embed/ihCVsaEMNzY) ; but I saw flickering on the LIME (it's an olimex device). I will try the patch on the LIME, plus latest mesa and latest kernel sometime coming week.

I upgraded to mesa 18.3, but now I am getting this problem:

# DISPLAY=:0 CLUTTER_BACKEND=x11 HD_NOTHREADS=yes CLUTTER_DRIVER=gles2 /usr/bin/hildon-desktop.launch

Disabling this extension makes a difference:

Not sure what changed in 18.2 -> 18.3 that makes my mesa think that the texture format is not supported (anymore?). Will require some debugging on my side, I guess.

Is there still interest in this, how is it in a recent version?

Yes, I am still interested. I will try to test it in the next few days.

Any update?

Sorry - give me a few more days.

Tested on the Pinephone "don't be evil" devkit. Mesa 19.3.0, Linux 5.4.y

Render problems are gone. Still observing some cases where X crashes, though.

I think as far as rendering problems go, this can be closed.

Thanks for the report, I'm closing it then.
