btw, I see the same layout issues in Chrome on Android 4.4 and L, phone and tablet. Same 1.572 version of Jenkins reported here. Safari desktop and Chrome desktop are fine. I have a screen grab if you want me to post it. btw, switching to desktop mode did not make a difference in the appearance.

kerrhome: It's deliberate on small screens. The switch happens at around 985px width on desktop screens for me.

Ah, I see. That makes sense. I didn't see this with our production instance of Jenkins (still on an older version). My Nexus 7 displays it the same "new" way (with 1.572), even in landscape, which I wasn't expecting, but I do like it. Thanks for the quick response. Now I know what to expect.

Daniel, if I have a trivial, small, cosmetic issue, would you like a ticket or shall I just post it here or email it to you?

Re Nexus 7, would be interesting to know what the effective resolution is. Could well try to render web pages on ~800px wide or so if possible to have them remain legible.

Het Shannon. Thanks for having a look at this. If you have issues you want addressed then either create a PR with a fix, or create a JIRA. If you have feedback/comments then you can email me or post them to the Jenkins dev list.

Is this fixed in 1.573? Can't see this fix in sources...

Probably will go into 1.575.

I still got this problem with 1.575 and IE8 on Win7 x86

Hi Marc... I think your comment is more relevant to JENKINS-23921 (IE8)
