[Bug 66623] Re: warning: GRClosure invoking callback: already destroyed

2008-07-12 Thread Ian McIntosh 
I'm still seeing this bug in Hardy.  And Owen's one-line patch still
solves the problem.

Is there any reason we can't ship Owen's one-line patch?

This bug was first reported almost 2 years ago.  If GTK itself had this
problem, it would be considered a show-stopper.  Why is it "Importance:
Low" for a GTK binding?

2008-07-13 Thread Ian McIntosh 
For app developers waiting for a fix, the following hot-patch seems to
work.  Testing for a range of version numbers before patching might be a
good idea.

require 'libglade2'

class GladeXML
alias :connect_without_source_guard :connect
def connect(source, target, signal, handler, data, after = false)
guard_source_from_gc(source)
connect_without_source_guard(source, target, signal, handler, 
data, after)
end
end

Just updated Jaunty to the latest and I can confirm that the rendering
glitch in atunnel is gone.

Thank you!

[Bug 155213] Re: IBM Thinkpad A21p - Volume, Brightness, and ThinkPad buttons broken with gutsy [regression]

2007-10-21 Thread Ian McIntosh 
I am seeing the same issue on a Thinkpad T23.

On-screen volume display worked in Feisty, but is broken in Gutsy.

One important fact: I boot with acpi=off, as APM works much better on
this laptop.

Is there any information I can provide that will help, or have we given
up on APM entirely??

I also see this in Gutsy.

The development system is upgraded from Feisty, and I had applied the
original patch manually, but I deleted libglade2.rb and did a package
reinstall to be sure I had the new Gutsy version.

Andy Owen's one-line fix has eliminated the problem, which was
previously easily reproducible.

[Bug 1169469] Re: ruler invisible

2013-07-06 Thread Ian McIntosh 
This could be related to the "window type hint" of the ruler window.

I remember having a hard time finding one that had reasonable behavior
on the desktops of the day.

If anyone on Unity wants to experiment with that, it's the
ruler_window.glade file "type_hint" field.

[Bug 680446] Re: Dragging does not work when ruler oriented vertically

2010-11-24 Thread Ian McIntosh 
Thanks for the report!

I haven't heard of this problem before.  Perhaps it is new in 10.10.
Dragging while vertical works fine for me on 10.04.

I will return to this after I upgrade to 10.10. If someone else wants to
investigate this in the meantime, that'd be great!

@Andrey thanks for the follow-up!

I'll close this bug as it seems unrelated to screenruler.

If you uncover any more info or solutions, please feel free to post it
here (for anyone else seeing the same problem).

If you feel screenruler could be changed somehow to work around this bad
behavior, please feel free to reopen this bug.

Thanks again!

[Bug 580449] Re: [i965gm] X often crashes when starting xmoto levels (i915 GPU hung)

2010-09-29 Thread Ian McIntosh 
Since upgrading to Ubuntu 10.04 (hardware details below), I can trigger
this behavior in an OpenGL app I'm developing, and I've narrowed it down
to very specific bits of fragment shader code.

In the fragment shader code below, if the GLSL uniform variable
'rgb_separation' is 0.0, this code runs normally (fast), if it's >0.0,
it outputs the "Error setting memory domains" error, runs at about 1
fps, and will eventually crash if left above 0.0 for a few seconds.

void main(void)
{
  vec4 color = gl_Color;
  vec2 tcoords = gl_TexCoord[0].st;
...
  if(rgb_separation > 0.0) {
vec2 offset = vec2(rgb_separation, 0.0);

vec4 left_pixel = texture2D(tex, tcoords - offset);
vec4 center_pixel = texture2D(tex, tcoords);
vec4 right_pixel = texture2D(tex, tcoords + offset);

color *= vec4(left_pixel.r, center_pixel.g, right_pixel.b, (left_pixel.a + 
center_pixel.a + right_pixel.a) / 3.0);
  }
  else {
vec4 texture_color = texture2D(tex, tcoords);
color *= texture_color;
  }
...
  gl_FragColor = color;
}

(Other parts of the shader use texture2D(tex, ...) to successfully read
from the set texture.)

(This happens both when 'tex' is a normal GL texture loaded from disk,
and when it is an image attached to a FrameBufferObject.)

So I've experimented a bit with this, and found that if I comment out
the "color *= vec4(...)" line then it does NOT exhibit the problem.

I've also tried splitting that line into individual expressions, to see
if that changed anything.  The code is below.  Oddly, if I uncomment any
line below besides the first, it then exhibits the problem.  With just
the red channel it runs fast (although it doesn't look correct).

color.r = color.r * left_pixel.r;
//color.g = color.g * left_pixel.g;
//color.b = color.b * left_pixel.b;
//color.a = color.a * ((left_pixel.a + 
center_pixel.a + right_pixel.a) / 3.0);

I'm not sure what to make of that-- but maybe it rings a bell for
someone.
