(Core :: Layout, defect)

Description

[No-Jun Park [:njpark]]

Attachment: test_calendar_flick_flame_12+2015-05-28-03-30-44.png

STR:
Open Calendar app
Scroll back & forth in day view
Change to week view, scroll left & right, then up & down
Change to day view, scroll left & right, then up & down.

Expected;
Views are displayed normally.
Actual:
At the top below the header, a black area appears while scrolling up & down.  It looks as if the area is not being drawn, because sometimes I see the desktop background through it

ni?ing :kat since this looks like a graphics regression shown in Calendar that came back, and at the time I was talking to him.  Do you think it's a layer bug?

Comment 2

[Kartikaya Gupta (email:[e-mail])]

It's not clear from your description if it's a graphics or layout issue; there could be a number of different root causes. If it's reproducible getting a regression window would be useful.

Comment 3

[Peter Bylenga [:PBylenga]]

[Blocking Requested - why for this release]:
Visible regression.

Window already requested.

I flashed to the reporter's build and was unable to reproduce this issue after several attempts.

I followed the steps in Comment 0 but no graphical anomalies were observed in day view.

Leaving the regressionwindow-wanted keyword for someone else to try.

Attachment: screenshot of issue

I was able to repro it on today's 3.0. I'm attaching a screenshot because it's not apparent on it of the issue. The repro rate varies from 1/~10 to 1/~50 scrolls; it should happen within 1 minute of scrolling.

Flame 2.2 seems unaffected. Scrolled for about 2 minutes without seeing graphical issues.

I won't be too hopeful in finding the regression window for this one due to low repro rate, but I'll try and see what I can come up with.

I meant to say the issue is not apparent on the original screenshot so I attached another one that shows it.

Gaia is the same so it's a Gecko issue.

David, can you take a look at this please? Looks like the work done on bug 1148582 might be the culprit here.

Comment 9

[Timothy Nikkel (:tnikkel)]

This sounds a lot like bug 1062792.

Comment 10

[Timothy Nikkel (:tnikkel)]

A fixed bug, so perhaps we need to refix it similarly.

Comment 11

[No-Jun Park [:njpark]]

If you leave the screen on, the black area actually flickers once in a while and displays a portion of the calendar view.

Comment 12

[Dylan Oliver [:doliver]]

Changing component based on comment 10.

Comment 13

[Mahendra Potharaju [:mahe]]

Patrick, Can you please check if this bug is fixed?

Thanks

Comment 14

[Peter Bylenga [:PBylenga]]

QAWanted to see if this is still occurring.

[Pi Wei Cheng [:piwei] (inactive)]

This issue is no longer occurring on Flame 2.5 and Aries 2.5. No black artifacts appear when scrolling in Calendar.
