r360961 does look like the culprit. juncai@: are you unable to fix? If so, I will revert the original CL. I am unfortunately unable to find a fix right now.

Comment 9 by, Jan 20 2016

I am unable to fix it. I am going to CC other reviewers of the origin patch r360961 to see if they know how to fix it.
BTW, the patch r360961 owner: is not at the CC list.

It should just get reverted.
An fyi, M49 already branched, so we may need a revert in branch also.
I am going to revert for now.
thanks much sadrul@

Make File-Picker modal on Linux

Chromium for Linux uses GtkFileChooserDialog for opening a file-picker,
but it is not modal to the X11 host window because GtkFileChooserDialog
can be modal only to the parent GtkWindow.

This patch allows the X11 host window to disable input event handling
to make a file-picker modal.

Design doc and discussion:

This CL was reverted due to the UI freezing problem that happens when the
users open a file-picker from a child window of the X11 host window:
