[/code:7bd09] Only with a CRT and TV connected... when i click on a menu on CRT, it wil be shown after 2-3 sec and Tv works fine...
Thx !

I've got the same problem with a second TFT connected.... I'm on KDE and the lag on opening a menu appear just with gtk applications (like vlc or firefox).

I use gnome.. :(

I am going to assume, because of the different hardware, that this is not
hardware config related. What i do see is that both of you are using dual
monitor setup. Looking at your config carlojekko, nothing pops out at me
that could cause a problem. This could very well be a problem with the
implementation of the dual monitor setup use with compcomm. I would ask
you guy's to please try using just one monitor to test and see if the problem
persist. If verified that dual monitor setup is in fact a problem with
compcomm we can then get with the devs to take a look at this as a verified
bug. I know this is asking a lot, but we want to make sure we are on the
right track before we get the devs involved. We don't want to waste their time
chasing a problem that may not be related to their code.

EDIT: Can both of you please let us know exactly what video card and how
much vram you have. Also let us know if you are using a custom kernel
with latency adjustments made. Verify if you have a "MTRR" setting in your
bios and make sure it is set to "DISCRETE".

Thanks

I try with a single screen and the problem is gone... all is ok !
With the twinview all is ok too.
I've got a nvidia 7600GtT with 256Mo with a Kubuntu feisty version and I don't use a custom kernel.

Excellent, thank you for verifying this. Ok now what we want to do to get the devs to check this out,
is to file a bug report. Please go here and input the symptom and a description of the test you performed
to verify this. This is the best way to get this bug fixed.

EDIT: I am also marking the title of this thread "BUG" so that it stands out to the devs.

[carlojekko]

I confirm... with one monitor is all ok!! I think it's only a problem with the gtk+... with qt and kdelibs (es. amarok) it works fine
I have
[code:b1c30]lspci |grep VGA
04:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600] (rev a2)
[/code:b1c30]
[code:b1c30] cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1
[/code:b1c30]

Eh, I should probably point out that this is a bit of a well known problem amoung the multiscreen-using opencompositing.org developers (==me).

Seems more like a GTK problem, but I haven't really given this issue much attention. There are several issues with these sort of setups, this is by far the most annoying that I have left once my multiscreen branch is merged....

It is on the todo list.

[olmari]

Heck I'm just glad it is on the to-do list (Remembers the original Beryl discussion about it).

Keep up the hard but hopefully rewarding work!

[carlojekko]

Compiz 0.5.5 doesn't solve this prob :(
But twinview solve this problem very well...
