Description Ionut Ciocirlan 2007-09-28 08:12:31 UTC
Version:            (using KDE KDE 3.5.7)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc 4.2.1 
OS:                Linux

Maximizing / restoring is extremely slow for konsole --real-transparency.

During maximization, X.org spikes with huge cpu usage (not noticeable during restore), and as far as i can tell, all video output is "frozen".

This is reproducible regardless of a compositing WM running or not.

I experience the same thing with gentoo and X.Org 7.3 - KDE version 3.5.7

This is from the X.Org log:

> mieqEnequeue: out-of-order valuator event; dropping.
> tossed event which came in late

Not sure if this is related, this is new with X.Org 7.3 though.
I can't remember having this problem with X.Org 7.2.

I am not able to reproduce this here, so I believe it is specific to a particular X.org setup or driver/video card combination.

Either way, I'm afraid that --real-transparency is an experimental feature in KDE 3 and is not something that I can support.

If you have the same problem in KDE 4 with --enable-transparency then that is a different story.

i can confirm the issue ( xorg 7.3, nvidia drivers, compiz-fusion ).
takes about 5 sec on a 2GHz Athlon

and it's interesting that it actually doesn't matter if i have compiz running or not using composite at all.

there seem to be more issues with --real-transparency, for example the cursor vanishes when i start typing.

Same issues here, KDE4-SVN (13 march 2008). I have X.Org X Server 1.4.0.90 (Release Date: 5 September 2007) and nvidia-drivers-169.12.
Comment 5 Ionut Ciocirlan 2008-03-27 05:19:59 UTC
As per comment #4, reopened.

> As per comment #4, reopened. 

The --real-transparency flag in Konsole (KDE 3) is experimental and there is not a lot I can do about problems with it.  

If you have a problem in KDE 4, where transparency is a supported feature, then please open a separate report.
Comment 7 Ionut Ciocirlan 2008-04-06 12:35:47 UTC
Oops, rather silly of me to presume they share the same code.
