Yes, as Daniel says.... please provide some screenshots with just a few extra tabs. Also.... can you test this on the very latest Jenkins and verify that it is the same please.

ok，i provide some screenshots,please see the attachments. version 1.574 is right ,but 1.575,1.576,1.577,1.578......1.584 all are wrong. i have tried the latest jenkins and verify it in ie 11 ,chrome,firefox. i guess it is all wrong after version 1.574 in many or all browers.

By the way, i have 14 views (include All view tab). But it looks correct when i create fewer views on newer Jenkins. see the attachements.

It's a strange one. The one's that look wrong look as though they are not using the newer tabs at all. I wonder is it something to do with one of the plugins you have installed? I notice that where it has fewer tabs (and it looks right) you have little or no plugins installed. Can you fire up that instance again and add a load more tabs and see what happens. It should wrap around.

Report needs to mention browser versions as well. Also, did you install a plugin providing an alternative tabs bar?

Also, are you able to reproduce the issue with many more tabs on the newly set up instance? If not, something else is going on.

Thank Daniel and Tom for your patiently reply. According to what you say i have uninstalled the plugin one by one. when i uninstall nested view plugin and custom view tabs plugin ,the view tabs look correct. At least ,i can use it . But the layout is not friendly. The brower is IE 11 version and Firefox 32 version . Chrome 37 version looks correct. You can see the attachements. If you think it is not a issue, you can close the bug. In any case ,thank you very much.

Sorry, my wrong. Chrome 37 version is the same as IE 11 and firefox 32. The layout is not friendly.

The screenshot name is "chrome many.jpg".

The line break issue has been brought up before. As this is an issue with the specific tab bar plugin you're using, I suggest you file a bug against that.
