TightVNC, DF Mirage driver and Firefox

Andrei B.
Hi,

I have just hit an odd problem with TightVNC and Firefox. It is similar
to an issue reported by someone about Firefox 4.

Win XP workstation, running TightVNC server 2.7.10 and DFMirage mirror
driver.
Assume a client with TightVNC viewer or RealVNC viewer. (both behave the
same regarding this problem).

Firefox is at 25.0.1, in fact all mozilla products at their latest version.

The problem just poped up this morning. Firefox window simply stopped
updating (anything other then the blue titlebar was behaving like a
frozen window, though Firefox itself was not frozen.
The odd part comes from the fact that Firefox window did update for
about 1.5 seconds after starting, and then stops.
The same is true for SeaMonkey. Interestingly however, Thunderbird did
not have the same problem.

I have started Firefox in safe mode, same problem.
I have uninstalled firefox, reinstalled it fresh, new profile. Same problem.
Same goes for SeaMonkey. Same goes for a system restart between
uninstall and install.

I uninstalled the mirror driver. Restart. Voila! It works.
Reinstalled the driver, restart, the problem happens again. Simply
disabling the flag to use the mirror driver in VNC server has no effect.

Also, I cannot confirm (yet) that Firefox screen updates on the physical
machine work or not, because I don't have access to it right now, only a
couple of days from now.

What is more concerning is the fact that I work with 3 systems with
similar configuration (though different hardware), all running same
version of OS, VNC and FF. Only one system exhibits this behaviour. I
can't reproduce it on the other two.
Actually, everything worked fine until this morning. The only thing
which may have had an efffect, I do not know what it could be or how to
remedy it, it was a power outage last night for the system with
problems. I ran the usual disk check routine (chkdsk).

If I uninstall DF mirage driver, restart the system, FF works, I start
FF, disable hardware acceleration from the Options, then close FF,
install DF mirage driver, restart the system, FF now works. (this is the
part similar to an older issue someone reported about FF4).

What went wrong?
What can I do to have it back working again?
I know it is only a performance detail, but it affects the local user,
and if it happeed on one system, it could happen on other systems as well.

Please help me locate the problem and hopefully solve it.

Thank you.

In reply to this post by WebDawg
Thank you.
That I did, disabled hardware acceleration in the browser.

However I do want to find out why yesterday it worked and today it does not work. (because of corrupted files from power outage? because of FF latest update?)
Also, why do I have 2 systems with the same software setup, the only thing different being the hardware itself (different video cards) which work...

Did Windows run an auto-update?  This could have changed 1 video driver but not the other to explain why 1 works and 1 does not.

Re: TightVNC, DF Mirage driver and Firefox

Andrei B.
No windows update, no driver update, no firefox update.
In fact, no update of any kind. Besides all updates are performed only after manual confirmation.

AFAIK Firefox updated from 25.0 to 25.0.1 one or two days prior.
And that is the only change.
However, Firefox is at same version across many systems. Only this one affected.

Seamonkey updated some time earlier the firefox, also affected.

According to Mozilla, Firefox uses some OpenGL to accelerate 3D stuff on XP, and some D2D to accelerate some 2D stuff, but only from Vista onwards.

Thank you.

 Hi,



 I have just hit an odd problem with TightVNC and Firefox. It
 is similar

 to an issue reported by someone about Firefox 4.



 Win XP workstation, running TightVNC server 2.7.10 and
 DFMirage mirror

 driver.

 Assume a client with TightVNC viewer or RealVNC viewer.
 (both behave the

 same regarding this problem).



 Firefox is at 25.0.1, in fact all mozilla products at their
 latest version.



 The problem just poped up this morning. Firefox window
 simply stopped

 updating (anything other then the blue titlebar was behaving
 like a

 frozen window, though Firefox itself was not frozen.

 The odd part comes from the fact that Firefox window did
 update for

 about 1.5 seconds after starting, and then stops.

 The same is true for SeaMonkey. Interestingly however,
 Thunderbird did

 not have the same problem.



 I have started Firefox in safe mode, same problem.

 I have uninstalled firefox, reinstalled it fresh, new
 profile. Same problem.

 Same goes for SeaMonkey. Same goes for a system restart
 between

 uninstall and install.



 I uninstalled the mirror driver. Restart. Voila! It
 works.

 Reinstalled the driver, restart, the problem happens again.
 Simply

 disabling the flag to use the mirror driver in VNC server
 has no effect.



 Also, I cannot confirm (yet) that Firefox screen updates on
 the physical

 machine work or not, because I don't have access to it
 right now, only a

 couple of days from now.



 What is more concerning is the fact that I work with 3
 systems with

 similar configuration (though different hardware), all
 running same

 version of OS, VNC and FF. Only one system exhibits this
 behaviour. I

 can't reproduce it on the other two.

 Actually, everything worked fine until this morning. The
 only thing

 which may have had an efffect, I do not know what it could
 be or how to

 remedy it, it was a power outage last night for the system
 with

 problems. I ran the usual disk check routine (chkdsk).



 If I uninstall DF mirage driver, restart the system, FF
 works, I start

 FF, disable hardware acceleration from the Options, then
 close FF,

 install DF mirage driver, restart the system, FF now works.
 (this is the

 part similar to an older issue someone reported about
 FF4).



 What went wrong?

 What can I do to have it back working again?

 I know it is only a performance detail, but it affects the
 local user,

 and if it happeed on one system, it could happen on other
 systems as well.



 Please help me locate the problem and hopefully solve it.



 Thank you.

In reply to this post by Patrick Shoaf
AFAIK, it's not only firefox, problem concerns also other programs that don't update their window content while mirage driver is installed :/ (You have to move window, only then it will be refreshed).

That I did, disabled hardware acceleration in the browser.

However I do want to find out why yesterday it worked and today it does not work. (because of corrupted files from power outage? because of FF latest update?)
Also, why do I have 2 systems with the same software setup, the only thing different being the hardware itself (different video cards) which work...

Re: TightVNC, DF Mirage driver and Firefox

Andrei B.
The window is not refreshed if resized or moved.

The mirage driver does a pretty good job otherwise, because if I play a video, it shows it correctly (all players except for VLC) and at good performance.

P.S.
I've uninstalled both mirage driver and tight vnc, restarted, reinstalled them, restarted.
No change on the problem.
