please help me test this, especially if you're using compiz

first, apply default skin (doesn't matter standard or unix)
then try resize tab like this , pull it up and pull it down a few times
and try resize you opera window and maximize/restore a couple of times.

now try this skin (I only changed a few lines of the default unix skin from rc2, it's named TESTING)

and do all the above, see if you notice any differences in responsiveness.

leave a comment about your finding and the OS please.

Wow! I don't know what you did, but it's much more fluid and responsive with your "TESTING" skin. I did notice a glitch with the panel arrow (left hand side, used for toggling the panel), but it seems to look very similar to the standard Unix skin.

I tested this on my 6 year old laptop, with an integrated Intel video card. With or without Compiz, it works smoother and more responsive than the standard Unix skin. (Compiz made no difference in performance that I could notice.) The following I found smoother: creating new tabs, resizing the tab thumbnails, resizing the Opera window, and restoring/maximizing the Opera window.

I never knew a skin could make that much of a difference! I guess it's more noticeable to me since I am using older hardware, and every little bit helps.

Because of the sidebar glitch (and the uncertainty of other glitches that I may have not bumped into yet), I will stick to the standard Unix skin for now.

Nice work. What changes made such a difference in performance?

Forgot to mention:
Linux Mint 9, 32bit
Intel integrated video

I want to add another finding / question.

I tested this on both 11.52 and 11.60rc2. In both cases, there was a performance / responsiveness boost as described above. However, the skin had fewer glitches / color mis-matches under 11.52 than it did under 11.60rc2. Was this meant for 11.52?

color mis-match? you mean some places such as main bar is black right? that's exactly what I changed (intentionally), [window skin] and [browser window skin] from system native to color = #000000 , and only this.

this is modified from the 11.60 rc2 default unix skin, so I don't see what the glitch you mean, maybe a screenshot and better discription?

here's hoping for more reports, I thought compiz is to blame since on my machine gnome-shell (using mutter) doesn't affect this.

Here is the TESTING skin under Opera 11.52: http://files.myopera.com/flansuse/albums/10048272/opera-11.52_testing-skin.png

Here is the TESTING skin under Opera 11.60: http://files.myopera.com/flansuse/albums/10048272/opera-11.60_testing-skin.png

Notice that under 11.60 it looks even more mis-matched? On 11.52, the only noticeable problem is the black "toggle panel" on the very left. I also discovered that 11.60 does not use the native GTK color on the top interface anymore! Even using the standard skin for Opers 11.60, it uses the wrong color, unlike 11.52.

yeah, I chose black so it's easier to find if someone(or myself) wants to look for what I changed, if you want to use this normally you can change the two place I mentioned to light brown or map it to some toolbar background skin.

Any idea why this simple change made such a difference with performance? Does using "native" really add CPU cycles when moving around elements in the GUI?

that's beyond me... somewhere in the compositing isn't as efficient as it could be maybe? linux isn't know for gui performance anyway.
I was hoping more reports can tell us which part is responsible for this, I mean gnome-shell doesn't have this problem at all, even applying skin is faster.
