[Touch-packages] [Bug 1977748] Re: Build Cairo with OpenGL support

2023-02-26 Thread Daniel van Vugt
I'm going to say no to this because:

 * Well-written code doesn't need Cairo to use GL to get the best
performance. Just don't re-render Cairo parts on important code paths.

 * Even if there were no known bugs in the GL backend, it would still
pose an unnecessary risk to the stability of mature components like GTK
and GNOME Shell. Probably more.

 * You can already build Cairo with OpenGL yourself and use that custom
build in your project.


** Changed in: cairo (Ubuntu)

[Touch-packages] [Bug 1977748] Re: Build Cairo with OpenGL support

2023-02-26 Thread Daniel van Vugt
I remember talking to the GNOME developers about this, I think it was in
person at a conference last year. From what I recall, they said the
OpenGL backend had issues so there was good reason to leave it disabled.
I don't know if it's the same reason as in comment #5, but it probably
doesn't matter because:

 * Apps using Cairo efficiently that keep the Cairo results in an OpenGL
texture most of the time already work just fine. It's only the render
and upload (glTexImage2D) stages that would be slower with the current
CPU rendering but a well-written app will never bottleneck on that.
Examples: GTK and GNOME Shell.

 * If you really need the OpenGL backend for some reason then you can
build Cairo within your project and embed it:

   ./configure --enable-gl=yes --enable-static=yes

[Touch-packages] [Bug 1977748] Re: Build Cairo with OpenGL support

2022-06-09 Thread Matt Wette
I was looking to run cairo on wayland.  A web search led me to the EGL
device.  I'm guessing by buffer you mean IMAGE surface (after digging in
the headers a bit).   I am happy to try that.  But I'm guessing at some
point in the future peeps will want it.   Thanks for digging in.

[Touch-packages] [Bug 1977748] Re: Build Cairo with OpenGL support

2022-06-09 Thread Daniel van Vugt
I always assumed Cairo was for software rendering only. That's how
gnome-shell and others use it -- render to a software buffer and then
upload that to a GL texture.

I guess the advantage of building Cairo with native GL support is that
it all happens on the GPU with less CPU time wasted... Although I expect
each app would need different code to support Cairo interfacing with GL
directly.

There would be no benefit to existing apps, only to developers of future
apps.

[Touch-packages] [Bug 1977748] Re: Build Cairo with OpenGL support

2022-06-09 Thread Sebastien Bacher
The openGL option was disabled a long time ago in Debian, the rational isn't 
really descriptive on the issue though
https://salsa.debian.org/gnome-team/cairo/-/commit/a4bad9f84

But we also disabled it around the time in Ubuntu due to bug #725434
with nvidia drivers, but comments from 2015 suggest the issue has been
fixed since so maybe we should give it another try?

Could you give some details on what improvement you expect building with
GL would bring?
