Do you mean how the bar's contents drop down into place (show near the end of your screencast)?

Yes, exactly. That's what I mean. Thanks. 

Unable to reproduce the issue on Mac 10.12.4 using chrome reported version-60.0.3078.0 , stable-58.0.3029.81  & Canary-60.0.3083.0 as per the below steps:
1. Changed system language to German
2. Ensure no other chrome windows should be in open mode
3. Launch new chrome (stable)   
4. Observed the 'bookmark bar' with junky animation for a new tab
5. Close chrome window
6. Quit chrome (CMD + Q)
7. Launch new chrome (Canary)  
8. Also Observed the 'bookmark bar' with junky animation for a new tab

Note:
We can observe 'Bookmark bar without junky animation' as per below steps:
1. Launch chrome once
2. just close the chrome window
3. Do not click Cmd+Q
4. Now again launch chrome by clicking on chrome icon

Please find the attached screencast for reference & let us know if we miss any steps to reproduce the issue.
Thank you..!!

Hm... thats is strange. I am still able to reproduce the issue with latest Canary, also with a clean profile. I am using a Non-Retina MacBook Air (Mid 2012). But I don't think that this could be a screen resolution issue?!

A further screencast is attached.

mehmet@,
Thanks for the reply.
Able to reproduce the issue on Mac 10.12.4 using chrome reported version-60.0.3078.0 , stable-58.0.3029.81 on Mac book Air  & Canary-60.0.3083.0 as per comment#4 screencast.

Observed 'content of the Bookmarks Bar appears with a janky animation' when we open chrome for the first time(no other chrome windows should be in open mode).

Observed the same behavior from M35 builds & confirming this issue to get more inputs from dev team.

jmukthavaram@: Thanks for checking it, but I don't mean the Bookmarks Bar itself. As shrike@ mentioned in comment 1, I mean the animation of the content of the bar (text, bookmarks) that is dropping down into place. That animation is differing between Stable and Canary Build. Thanks.

Something changed here in latest Canary 60.0.3091.0.:

The "dropping down" issue seems to be fixed. But now when you start Canary, the "Import Bookmarks" text is to see for a second, before all bookmarks and folder appear on the Bar.

A screencast is attached.

mehmet@ what are your machine's specs? 

I haven't been able to repro either this issue or the one from earlier in this bug, and I'm wondering if there's some sort of hardware difference that's causing the bar to come in slower.

Hello lgrey@, I am using a MacBook Air 11" Mid 2012 and a iMac 21,5 End 2012. Both have NonRetina Displays. I am seeing it on both machines.

I am wondering, because it doesn't happen in latest Stable.

Enclosed a screencast Stable vs. Canary.

Thanks for looking into it.

[Mac] Hide bookmark bar empty view by default

This is a speculative fix for  crbug.com/714407 ,
specifically the post-refactor manifestation in #10. Speculative
because I can't repro.

mehmet@ is this fixed now?

Hello lgrey@,

Yes, thank you. It is fixed in latest Canary Version 60.0.3095.0. The "Import Bookmarks" text is no longer to see, before all bookmarks and folder appear on the Bar.

But the initial "dropping down" issue is now in Beta (M59). What do you think, should we leave it as it is in M59, because we do not know what could have fixed it?

I know how to simulate the issue now, so I could theoretically get an older checkout and maybe come up with something that could be cherry-picked to M59. My feeling is it's probably not worth it. shrike@ what do you think?

Seems like the change is small, so cherry-picking back to M59 is not super risky. If you can check out M59 and reproduce the problem and confirm your cherry pick fixes it there it's probably worth it.

shrike@ to be clear this would be a different fix. The original issue was (I think) fallout from NIB removal, this fix relies on the new layout code to do its thing.

Tested this issue on Mac-10.12.4 using chrome version 60.0.3095.5 as per comment#13.
Issue 1-> The  "Import Bookmarks" text is no longer to see, before all bookmarks and folder appear on the Bar.
Observed this issue got fixed.

 Issue 2 ->Bookmarks bar droping down janky issue.
Still issue observed.

Please find the attached screencasts of both fixed(Issue 1) &  issue 2  behavior.

Thanks.

Can we split the non-regression into a separate bug? I'd like to look at it eventually since views has a smooth animation instead of it popping in and out, but I don't think it's a P1 or related to the issue mehmet@ brought up.

shrike@ ping re: #16

lgrey@ - I'm confused on what's what here (sorry). We can discuss on Monday, or set up a GVC for this week if that's too long to wait.

Archiving old bugs that have only received trivial updates for some time.

If you feel this issue should still be addressed, feel free to reopen it or to file a new issue. Thanks!
