Another potential (minor) issue:
The task bar shows the old icon for me.
If I hover the mouse over the task bar icon, the thumbnail view that pops up shows the new icon in the window’s title bar. The actual window’s title bar also displays the new icon.
I’ve logged off and back on, but I haven’t restarted after installation.
Windows 7 Pro 64-bit.
@guillermooo : i was having the same issue. I signed out and signed back in and it worked for me . You said that you have already done this , can you please try restrting your system ? I dont think this is a ST issue… I am on Win 10.
I won’t go to the trouble now, but I suppose it’s a temporary thing, yes. Just wanted to point it out in case I forgot about it.
@jps What a restart won’t fix is that the site is still using the old logo! 
(I’ve Ctrl + F5’d my browser a couple times.)
My themes (Seti, Seti_orig) are broken after update.
Is that expected with all the changes?
Seeing empty sidebars, empty folders and “ghost” icons here too. Switching themes seems to clear it temporarily. On MacOS 10.12.4.
Edit: seems to be mostly not rendering updates properly. Anything that triggers a re-render fixes it.
you can clear your taskbar/Windows Explorer icon cache to get it to update, without needing to log out of Windows:
@jps @wbond thanks for this update! Looking very nice!
One thing I’d like to see is the ability to set a different height and some padding around the OSX toolbar. This would make things feel a little less squashed.
I think more likely yes than no. Theme developers should review their themes, because of some possible incompatibilities. Details in the Depracated and Obsolete sections. However I think that only very popular themes will be updated, because many of them are not maintained anymore by their authors.
The good news is that new theme engine allows to create really awesome UI. So I recommend to stick with Default theme and wait a couple of months to see new UI game changers.
P.S. Package Control needs rating system, because of many obsolete and low-quality packages.
Congrats!
I got some very weird scaling issues when moving the ST window from a retina to non-retina display
Hi @wbond!
Well, I had it disabled before updating and then nothing get’s shown. If I enable Show open files, everything is visible. When I disable it (because I don’t want open files shown), then it works. But if I restart Sublime or close the window, I got the same problem that nothing is shown.
Would be great if this get’s a fast fix, thanks!
On 3128 and same empty sidebar problem for me. It’s nice to have a work-around by going to View > Side Bar > Show Open Files but annoying because it keeps reverting back.
I get some ugly fonts (looks hard/frayed):
How about using the same (monospace) font you define as font_face in your settings?
This is a pretty random thing, but I am using the dark theme on MacOS and I am not crazy about how the background color of the new Sublime Text icon matches PERFECTLY with the background of the dock/app switcher:
Perhaps that was intentional, but would you consider darkening or lightening the background a bit?
Here’s how you fix it: change the colour of your desktop. Or you can turn off transparency:
If you don’t want to change your desktop environment and are not opposed to replacing the icon yourself, I find Rafael’s macOS flavored version to be far more pleasing and platform consistent than both the new and old official icons.
By the way, I 
the Adaptive theme.
One thing I’d like to see is file type icons though. That’s all I miss from themes such as Primer.
I think this is typically best handled by the community: https://packagecontrol.io/packages/A%20File%20Icon
was it intended that autocomplete in the new Theme - Default no longer shows which characters matched?
