1134704 - Nightly doesn't render pages when opened via RDP session on Windows 7

Status: RESOLVED DUPLICATE of bug 1135247

(Core :: Graphics, defect)

Description

[Jens Glathe]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150218030228

Steps to reproduce:

Nightly is installed on a windows 7 machine. Log in, work a little, RDP from another machine (Win7 or Win10 TP, both have the effect).


Actual results:

If Nightly was open at RDP login time, it will function "normally". If it wasn't open, or is completely closed, and you start it in the RDP session, it will start, but won't render any page.


Expected results:

It should render the page regardless if it's started anew or not.

Any error messages in about:support graphics section?

Hi Milan,

just tried, about:graphics doesn't render anything, too. But before that, Nightly crashed... tried to open two windows with links opened from emails. That's another curious thing: when a link is opened (from an email, for example), a new window opens and the page will be rendered. If you enter about:graphics into this window, another will open and both don't get rendered. So... something a bout inheriting a graphics (presentation space) handle, perhaps?

with best regards

Jens

To be clear - about:graphics doesn't render anything when you directly access the machine as well, or just through remote desktop?  Or do you have a non-RDP access to it?

Attachment: That's what I get with about:graphics

Well, about:graphics returns an error, since a few days... it has been working before.

Via RDP I do get a blank page, though.

If you unset E10S in the preferences, does the problem go away?

Comment 8

[Jens Glathe]

Yep, that's it. Just tested. E10S is on: strange things happen. E10S is off: starting Nightly works also in the RDP session. about:graphics fails, though.

Funny, I asked for about:support graphics section but once Jens called it about:graphics I just continued using it without even realizing it :)
