1156833 - Screen sharing: Blank windows and dialogs on 10.6.8

Status: RESOLVED WONTFIX

(Core :: Graphics: Layers, defect)

Description

[Stefan [:stefanh]]

Attachment: Blank window with sheet rendered fine

[Tracking Requested - why for this release]:

Running 10.6.8 on an old Mac mini with Intel GMA 950, I still see a blank window even though bug 1151644 is fixed.

I used the inbound tinderbox builds to track the regression to https://hg.mozilla.org/integration/mozilla-inbound/rev/295db120bf12 which is the third patch in bug 1125848.

Flipping layers.acceleration.disabled doesn't make a difference. The warning sheet that appears when you try to close a window with multiple tabs renders fine, though.

There's a log file in bug 1151644 from running with the patch there on the 10.6.8 machine, if that can be of any help: https://bugzilla.mozilla.org/attachment.cgi?id=8592930

Oh, and I access this machine from a 10.9.5 system (Intel HD Graphics 3000) with Screen sharing.

Is this planned work for 40?

Comment 3

[Milan Sreckovic [:milan] (needinfo for best results)]

I don't see this making it into 40, at least not because of the priority - the version of OS X and the workflow don't make it a critical fix to rush.

[Stefan [:stefanh]]

It's probably the Intel GMA 950 graphics that matters here. If anyone has ideas, I'll be happy to test.

Comment 5

[Stefan [:stefanh]]

So, I've tested this a bit more and I think it's a rather rare case:

1) It only happens when accessing the machine remotely. If I attach a monitor to the machine, I don't see the issue.
2) I don't see the issue if I access the machine's 10.7-partition remotely.

I adjusted the summary a bit since it does looks like this is dependent on just the OS version.

[Lawrence Mandel [:lmandel] (use needinfo)]

This is a lower priority bug. I have dropped tracking and marked 40 as wontfix.

Comment 7

[Stefan [:stefanh]]

We don't support Mac OS X versions below 10.9 now, so I'm resolving this as wontfix.
