I'm using kwin itself, which already has some decent compositing effects. |
12 |
I've been using mainly the transparent windowing features for quite some |
13 |
time (the others, shadows did little for me, and I got tired of waiting |
14 |
on the fading effects when I wanted to get stuff done, so I turned that |
15 |
off). With xorg-7.1.1 and <kde-3.5.6 using EXA rendering instead of XAA |
16 |
(which was very slow with compositing turned on in 7.1.1), the transparent |
17 |
windows weren't CPU intensive at all, even on my older Radeon 9200 running |
18 |
dual 1600x1200 in merged framebuffer mode (stacked for 1600x2400). The |
19 |
biggest problem I noticed was a bit of kompmgr/kwin memory leakage -- kept |
20 |
under control with decently strict ulimit settings on virtual and resident |
21 |
memory -- and a desktop copy of a script to killall -9 kwin; sleep 1; |
22 |
kwin, thus reclaiming the leaked memory when things got slow because it |
23 |
was running up against the resource limits I had set. |
24 |
|
25 |
With xorg-7.2, EXA had some bugs (blank/missing pieces of windows and the |
26 |
like, it's a known issue), but XAA is fast enough to be usable now, where |
27 |
it wasn't really usable with composite before, at least here. Thus, I |
28 |
switched back to XAA. The leaks seemed to be somewhat worse for a few |
29 |
days, but kde-3.5.6 came out just days after xorg-7.2, with some major |
30 |
memory leak fixes for those running composite, and indeed, it's /very/ |
31 |
stable now -- I've not had to use that kwin killer script at all since the |
32 |
kde-3.5.6 upgrade. I've been going to try EXA again and see if the newer |
33 |
3.5.6 KDE fixes the bugs with it too, but I've not yet. |
34 |
|
35 |
FWIW, my general window opacity settings are |
36 |
|
37 |
Active: 93% |
38 |
Inactive: 60% |
39 |
Moving: 77% |
40 |
|
41 |
I have the checkbox to treat "keep above" windows as active, checked. |
42 |
|
43 |
Taking a look at the Beryl 2 previews, the spinning cube eye candy looks |
44 |
nice, but I have a number of Window-Specific Settings that AFAIK need kwin |
45 |
to work, so while I might try Beryl at some point, I expect I'll be back |
46 |
to kwin when I actually want to get back to work, and will be waiting |
47 |
patiently for a truly KDE integrated version in KDE4. |
