Slow, laggy window resizing for gnome-terminal and Qt

[robeen]

Binary package hint: compiz

After upgrading to Jaunty there is a very frustrating delay when resizing terminal windows (only terminal windows).

After the mouse button is released it takes 2 seconds before the window get resized.

It only happens with compiz enabled.

Release: 9.04

Additinal info:
After the upgrade I had to add this to fstab to be able to start a terminal.
devpts /dev/pts devpts gid=5,mode=620 0 0

And some strange behavior I noticed.

This works fine..
$ gnome-terminal

But not as su..
$ sudo gnome-terminal
Failed to contact the GConf daemon; exiting.

I also see the same problem with my gvim windows, as well as gnome-terminal and plain old xterm. There is a 2-second delay before any window resize operation, and the resize animation moves in 2-second jumps. Getting the window to the desired size is extremely difficult.

I'm using the ATI binary X server:

Duplicate bug 377539 has a good video of the slow resizing.

[Robert Ancell (robert-ancell)]

Bug 377539 also notes in their case it is only for QT windows, not GTK+ windows.

[Bartek (tschew)]

Hi Robert, I reported Bug 377539, while QT applications are affected as a group, gnome-terminal is also affected, as described in this bug.

Maybe there's a delay in a specific call querying window dimensions as compiz informs the user about gnome-terminal and xterm size in terms of characters (which I presume it computes from the window dimensions). Maybe QT uses the same call while most GTK+ apps rely on a different call.

As an experiment I've enabled "Show resize info for all windows" in compizconfig. This introduces the delay for ALL windows.

Disabling the plugin completely (so that no size information is SHOWN even for terminal windows) does not remove the delays in resizing terminal windows or QT windows. This suggests to me that the queries are still made but simply not displayed.

[Bartek (tschew)]

It might be useful to add that the problems seem to be graphics card agnostic as I have both an embedded (G35) intel machine and an nvidia 260gtx machine which are affected in the same manner.

[aleksey (shaferov)]

Same problem.

Disabling of deco is plugin helps much.
Resizing without deco is like without compiz at all.

Sorry for bad English

hi,

my T500 (Ati 3650 mobil) has that bug since ubuntu 9.04. It gives me the willies.

pls help

I don't know if it is the same problem but when activating the desktop effects, maximizing or opening new windows is very very slow except for VLC!! I have an ATI HD3430. I thought the problem is related to the fglrx driver but since other users with different graphic cards have almost the same problem I think it's a compiz bug. Sorry for my English :p

have the same problem. resizing and maximizing of windows is very laggy..

Sorry to bump, but I still have the same issue and it's been 3 years. Anyone any ideas?
