and it reminds me of http://crbug.com/675265 (no idea if it's actually related)

If you initiate a download from profile A, then the file chooser will appear in profile A and the download will be placed in profile A. If that's what's happening, then I'd argue that things are working as intended. I'm not sure I follow why the dialog should appear on another profile.

There's a much more confusing case if you teleport a window from one profile to another (using the "Move to ..." option after right-clicking a window frame). The UI flow for downloads initiated from one of those windows tend to be pretty confusing.

I'll leave it up to the downloads and FileManager folks to sort out :)

The issues linked in #1 are unrelated.

The behavior described in #3 would make sense but that's not what happened.

nb no teleporting is involved here.

To clarify the steps were
In profile A, start a download
Before the download starts, switch to desktop B
Save dialog appears _on desktop B_
File is saved to the Downloads directory of B

warx@ is this a dupe of the other issue you fixed recently?

It doesn't sound quite like the case https://codereview.chromium.org/2599833003/ is fixing for. Maybe save dialog should not show on current desktop?

Yes. I think the right way to fix it is to make sure the save dialog always shows up on the desktop of the user who initiates the download. 

Actually I cannot reproduce it on either tot or 56.0.2924.87 on my personal link. Any other specific conditions?

For me, I was downloading a folder, and while it was doing zipping, I switched to the corp desktop. But the save dialog is still shown on my personal account's desktop...

Reproducible for me on Version 57.0.2987.32 beta (64-bit)
Platform 9202.18.0 (Official Build) beta-channel panther
Firmware Google_Panther.4920.24.26

after a couple of attempts, just as described above

OK, I could reproduce it on about 1/7 attempts, plus the one original occurrence the other day. I don't know what was different on the cases where it occurred, maybe just timing?

Perhaps flipping between screens while the download is preparing causes it?

Hi, I tried several times (flipping screens while waiting for download), still never got a hit.

I am a little concerned about chrome version. I would like know if it happened after 56.0.2924.96 or 57.0.2987.42, since there is a CL landed and merged to these two versions.

Background: there are two kind of regressions of multi-user starting from M-56, one is fixed and merged, the other is just landed on m58 not merged. If we could know if there is a repro after 56.0.2924.96 or 57.0.2987.42, that will help a lot. Thanks!

My Panther is on 57.0.2987.85 and I can't reproduce this after a few
attempts, but as noted above it is intermittent. So, maybe it was fixed? I
will let you know if I see it again.

Ok, please reopen it once it is seen again.
