Coordinates sent to HI-DPI linux environment are about doubled

Reported by scootalo...@gmail.com, Mar 13 2018

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.146 Safari/537.36

Steps to reproduce the problem:
1. Enable iBus
2. Type in any input field

What is the expected behavior?
Selection table right under input

What went wrong?
Character selection table manages to get far away from the input field, sometimes even outside of the screen

Did this work before? N/A 

Chrome version: 65.0.3325.146  Channel: stable
OS Version: 
Flash Version: Shockwave Flash 28.0 r0

Issue found in GNOME 3

It seems that ibus devs or gnome devs has patched
https://bugs.chromium.org/p/chromium/issues/detail?id=475718
on their end, now being gnome desktop scale aware and double the coordinates itself when hidpi is detected

Other apps work properly

Applications that used to have the problem of selection table being left and above them has no problem now, indicating that https://bugs.chromium.org/p/chromium/issues/detail?id=475718
this fix might have to be reversed now.

I'm currently on fedora 27, Gnome 3.26.2.
Now submitting screenshots from a complete new user, using latest the latest stable chrome build from Google. 65.0.3325.146.
Can you please check if ibus works properly for applications other than chrome/chromium? Here it works for all GTK apps such as libreoffice, gnome-terminal, as well as KDE app like kdenlive, while having issues on Chome.
Oh and where can I obtain a copy of official canary for linux? (pre-built as rpm would be nice)

Sorry for the typos in the previous comment, here attaches a screenshot of chromium from the fedora 27 repo, version being 61.0.3163.100.
Interestingly this older build of chromium has no such problem, not sure if patches were applied by fedora repository maintainers.

Unable to reproduce this issue on Ubuntu 17.10 using reported version 65.0.3325.146. As mentioned in comment#3 and #6 this might reproduce only on fedora.

As ET team do not have Fedora with us, could someone from Inhouse team please help in triaging this further. Hence adding TE-NeedsTriageFromHYD label.

Thanks! 
Reporting the same issue on chromium 63.0.3239.108 from fedora's repo
Looks like it is related to gtk2->gtk3 transition since 61.0.3163.100 in comment #3 still has some gtk2 dialog boxes (file selection mainly), while the newer version has gtk3 dialog boxes.

Re: comment 9
Does it work properly with other apps? I suspect that it's an ibus/gnome thing with he newest version since it used to break in everything but chrome, now not broken in everything but chrome.

Such an issue is reproducible in Version 67.0.3396.48 under Ubuntu 18.04, with Gnome 3.28. 

Just to add a few details: 

1. The input selection works when typing in Chrome's address bar. However, the selection window would be nowhere to be found if the typing was done in window elements of a website.

2. Same issue when typing in Chrome extension such as Google Hangouts.

+shuchen This seems similar to another bug that was ibus-related.
