Thank you for the bug report. Will keep this in mind in case I can find repro steps.

My wife is reporting a variant of this problem as well. For her, it's pasting images from the clipboard (generated from screenshots via cmd-ctrl-shift-4) into new messages in gmail.

She's running Chrome 71.0.3578.98 on Mac OS 10.13.6.

I have briefly tried to repro it on my Mac (running the same version of Chrome on 10.14.2) with no luck, but she does this action constantly, so she has a lot more data points than I.

This sounds similar to bug 873497, which it looks like was resolved inconclusively; +erikchen, +avi, and +pkling from that bug.

pkling / cjamcl - can you check which version of the OS you're running? I'm going to have her upgrade to Mojave (I thought she was already running that) and see what happens.

Also, any tips / thoughts on what you might look for, debugging-wise, in case her computer gets into this state and I can poke at it?

Thanks for the report! I'm able to replicate it now.

mac os version: 10.13.6

open textedit, type "TEST"
open chrome, go to google.com
take screenshot (cmd + shift + f4). seems any size works.
copy "google" from address bar
copy "TEST" from textedit
paste in chrome address bar

expected: "TEST" in address bar
actual: "google" in address bar

to get out of this state (simplest I could get it):

open another text editing program (not textedit. I used sublime). Type "TEST2"
copy the chrome address bar (full selection via a triple click)
paste in the text editing program
copy "TEST2" from the text editing program
can now paste "TEST2" in chrome

now, bad news (or good news, depends on your perspective). I think you can replicate this behavior across any two programs in OSX. Open up sublime and text edit, take a screenshot in one and copy some text, then paste in the other editor. It's almost like taking a screenshot creates a "fork" in OSX's clipboard, making each program have it's own state.

#6, Thank you for the repro steps.

Unfortunately, I'm unable to repro using them on macOS 10.13.6/Chrome 71.0.3578.98 while using either cmd+c/cmd+v or right-click>copy/paste to copy/paste. I'm using cmd+shift+4 (instead of f4) to take a screenshot though, if that makes a difference, since that's how the touchbar mac takes screenshots.

I have tried repro'ing this between VSCode and textEdit as well, with no luck.

I have the same Mac, and was actually doing cmd + shift + 4 like you. Also Chrome 71.0.3578.98.


A friend was able to repro. He has the same version of Chrome and OSX.

I've been able to repro now, through using cmd+shift+ctl+4 to take a screenshot (still can't repro via cmd+shift+4). Including ctl for the screenshot puts the screenshoted image onto the clipboard, and seems to "fork" the OSX clipboard, as you mentioned. After the screenshot+copy, these 2 programs only see items copied from the same application.

Apologies to my lack of attention to detail. It is only cmd+shift+ctl+4 that repros. I typed the shortcut from memory, but it turns out it's really just in my muscle memory :)

No worries. Thank you for providing the repro. :)
