Sorry I couldn't reproduce the issue on 54.0.2840.99 m (64-bit) on Windows Server 2008 R2 SP1.

Could you provide the platform info? Windows 32bit or 64bit?
Is it reproducible on incognito mode, another device, another user?

Hello Soushi,

I was able to reproduce the issue on a Windows 7 and 10 computers, using Chrome 64 bits and 32 bits versions 54.0.2840.99, Beta (55.0.2883.59) and Canary (57.0.2931.1), This issue is happening to any user signed-in to the browser or not, I also test it on the incognito window on each versión of Chrome and I’m able to reproduce the issue.

Able to reproduce the issue on the latest canary(57.0.2936.0), latest stable(54.0.2840.99) on Windows-10. Works fine on Mac OS 10.11.6 and Linux Ubuntu 14.04.

Regressed in M-39:

Last good build: 39.0.2132.0 [Used to show warning dialog when trying to save the pdf]
First bad build: 39.0.2133.0 [Nothing happens on clicking the save as pdf]

Looks like the author of CL(erikwright@) no longer works for the project. Hence assigning to jschuh@ as one of the reviewer of the CL for help in finding an appropriate owner for this.

Thank you!

 

thestig@ can you take a look and determine where this belongs?

Followed the steps in comment 6 and I cannot reproduce this on Windows 10 64 bit with latest stable (55.0.2883.87) or canary (57.0.2966.0). It successfully saves the e-mail with the long subject line as a PDF. Tested with a number of different settings; what were the settings when the problem occurred? (Headers/footers, background graphics, pages, orientation, page size)

Tested again today on stable (same as before) as well as Canary (58.0.2990.0) and still can't reproduce on Windows 10. Is this still an issue?

Reducing priority as it is a corner case and hard to duplicate.

Closing as I cannot duplicate this and have not received feedback. Please re-open if this problem recurs on the latest Canary/Stable.
