Chrome Version:69.0.3497.23 (Official Build)Revision a0f931c424245a817bf2ad63eb45c6c95f28e1ee-refs/branch-heads/3497@{#301}(32/64-bit)

What steps will reproduce the problem?

(2) Open www.drive.google.com, try uploading any file of approximately 5 GB and navigate to chrome://net-internals/#quic
(3) Observe Packets lost

This is non-regression issue.

2. This issue is not seen on Mac OS

Correction : This issue is also observed on Mac Retina (10.14)

Please find shared the QUIC script file (Windows) in a drive (https://drive.google.com/open?id=1trU22ptfeakPl3mR_OzH_52XIdkrZQUn).

Hm. The attached net-internals does not include the QUIC session from the screen shot, I think. The screen shot talks about connection_id 11282408... But I don't see this connection id in net-internals.

That being said, I'm surprised not to see the NSTP connection option in the CHLO. I'm curious. If you add the option specified in https://bugs.chromium.org/p/chromium/issues/detail?id=862555#c20 does the problem persist?

It looks like this Chrome is launched by command line with flags. So I guess the finch NSTP doesn't plumb here.

Could you add the command line switch "--force-fieldtrial-params="QUIC.FlagEnabled:connection_options/NSTP" to your script before "--no-proxy-server". Run the script then and see if that fix the issue?

With response to comment #4 :
Retested this issue with enabled command line switch "--force-fieldtrial-params="QUIC.FlagEnabled:connection_options/NSTP" on Win (7,10) and Mac (10.14) Machines using Dev build # 69.0.3497.23 and the issue still reproducible i.e Packets lost is observed while uploading file to Google Drive.

Please find the shared QUIC script file and Error log file (Windows) for the same in drive (https://drive.google.com/drive/folders/1trU22ptfeakPl3mR_OzH_52XIdkrZQUn).

Attaching screen cast for the same.

Thank you.
