This is on trunk? Nightly? It's working fine for me on Mac... Do you have a bajillion groups open or something? It was working fine before?
Yep, trunk nightly. I only have 3 groups, but probably 70 tabs. I don't know if it was fine before or not, since I don't go into the tabview UI very often (only a lot lately, since my groups keep getting horked and I have to fix them).
Tim, are you seeing the same on linux?
Mhhh.. It's okay and usable for me. My machine is not the newest/fastest anymore but for me there's no noticeable regression. Maybe we could get Dietrich to do some profiling to know what his machine is doing while dragging groups around? :)
Mozilla/5.0 (Windows NT 6.1; rv:2.0b10pre) Gecko/20110125 Firefox/4.0b10pre Moving around groups tends to be bumpy. Tried it on WinXP and Win 7.
Dietrich: need specs on your hardware; if it's OSX running 10.5, we recently turned off GL, which might be slowing things down there. Either way, I don't think this blocks, but for the purposes of investigation, it'd help.

If someone could do some js and/or shark profiling on this, it would be appreciated. My guess is that either, indeed, we're spending time with graphics and drawing, or we're using cycles in the snapping code. One way to quickly see whether it's the snapping which is costly is to see if dragging performance improves greatly if you hold down the option key and drag groups around. This turns off the "snapping" to other groups and tabs. Also, if someone could identify a regression range, that would also be helpful.

Video: https://people.mozilla.com/~dietrich/tabview.ogv Note how the dragging is seconds behind my mouse actions, and the snap lines don't show up ever. (I'm not holding down ctrl during this. Doing so did not change the behavior.)
(In reply to comment #11) > Video: https://people.mozilla.com/~dietrich/tabview.ogv Wow, this strikes me as particularly bad. It is not what I see on my mac with recent builds. :/ Would it be possible to get some profiling?
Dietrich, does this still happen for you with the latest nightly? I'm curious because bug 606148 has landed yesterday.
Dietrich, in the video you're dragging a stacked group... is it the same for unstacked groups?
Still happening, and happens for any type of group. If you come up with a patch I could apply that would dump out profiling information, I'd be glad to apply it and get that info for you.

The final beta window has essentially closed, but I would be happy if we could do some profiling for this post beta12, though a fix itself (if necessary) most likely can't happen for fx4. :(
If the fix is not large footprint, seems not risky, has great test coverage, then drivers are more likely to take it. I wouldn't let the risk of it not being taken slow any momentum for fixing this.

We're not going to address this with Panorama being slated for removal.
