Comparision of normal vs slideshow views

Jan's fix for Bug 819614 uncovered two move hidden bugs. Bug 75209 and this one, where the grey gradient bar is not rendered in the slideshow view mode. It's an insidious bug, as the objects will show in the normal view.

Steps to reproduce:
1. Open attachment 106028 [details] document in Impress
2. Note the gray box behind the pictures
3. Start the slideshow. 

Expect results:
Gray object sows in both views.

Actual results:
Version: - Grey Gradient Rectangle: shown
Version: 4.4 - Grey Gradient: missing

Hi Luke,

I confirm gray gradient rectangle is visible in:
LO Build ID: f9b3ad49d92181b0a1fe7e76f785a2c2cd0847d3
an not visible in:
LO Build ID: 5aeb852efcabdd51545d5d41c92f4bf3cef1d663
TinderBox: Win-x86@39, Branch:master, Time: 2014-09-08_07:01:57 
under Windows 7 Home Premium.

Add a border to the rectangle make it again visible.

I believe I'm following the repro steps as provided. I'm just confirming that there's a gradient rectangle in the given slide, as it appears in the comparison image, right?

Testing with Ubuntu 14.04 x86_64:

LO Version: - BAD - Has two separate skinny vertical gradient rects.
  Build ID: fc49c052dbdbb5ab3b0a02a13143705f769b9662

LO - GOOD - Gradient rectangle is visible
LO Version: - GOOD

   Time: 2014-12-09_22:40:23

Luke: Is this one fixed?
Comment 4 Luke 2014-12-11 01:00:09 UTC
Yes, there is a gradient rectangle that goes from White to dark gray in the lower left-hand side. You can select it and move it around in normal mode. Note the white area where the gradient starts in normal view. When you go to the slideshow mode, the rectangle is not rendered like attachment 106579 [details] .

I tested with a build from today, Build ID: 629a705c127661111c54e14035b55850e36c2167, and the slideshow mode is still not rendering the rectangle under Win 7. Are you testing in slideshow mode? If so, maybe this is a Windows only bug now.

Ah, okay -- all clear to me now :-)

CONFIRMED with same LO Version I tested above: (Build ID: df62a2)

(Testing on Ubuntu 14.04 x86-64 again)

The gradient looks correct in both normal and slideshow views in LO (attachment 110704 [details]). It looks correct in slideshow view in LO Version: (Build ID: dea4a3b9d7182700abeb4dc756a24a9e8dea8474), but looks like two separate vertical rectangles in normal view (attachment 110706 [details])

Comment 9 Luke 2014-12-14 19:05:38 UTC
I have manually bisected this regression down to 

svx: fix VML export of rectangles imported from drawingML

The commit before that, 71aa91ab7e16be70ed9abd0959f8f18d35439acc was GOOD. Could you please look into why gradient boxes are not displaying in slideshow mode now? Note the regression that caused the smooth gradient to be stripped in norm view has been fixed in recent builds. 

Thanks for everything!

Someone resolved this issue recently. Great job team!

Comment 11 Luke 2015-01-12 19:31:00 UTC
Strange interplay of bugs/fixes here. I bisected the fix down to:

So the source of the bug was actually:
commit bb5c7d6a79309236d4f19bb2498f2e850f735a2f
fdo#38844 Reduce XOR clipping for gradients

Miklos' patch probably just triggered it, but was not been the root cause.
