1075111 - Large image loaded in e10s tab acts strange, has issues with painting

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[Jim Mathies [:jimm]]

STR:

1) open an e10s browser
2) in a fresh tab, open
http://people.mozilla.org/~mmaslaney/e10s/Firefox-e10s-v4.png
3) you should see the magnifier plus cursor over the image, click once to expand.
4) open a new tab, flip to it
5) flip back to the image

result: black tab content, nothing is drawn.

6) click about where the image would be (you should have a magnifier minus cursor) to contract the image down again.
7) flip to the other tab, flip back

result: image is displayed properly

goto step 3, rinse, wash, repeat.

This was on Windows. On Mac, we are seeing strange zoom behavior, but the image apparently paints properly.

Works for me with todays Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:37.0) Gecko/20100101 Firefox/37.0. Bad hardware acceleration may be a factor for this issue.
