Hey @JAnD,
thanks again for your feedback on the help page and the ticket here.

To your screenshots: That looks really nasty. Under what operating system do you use VIvaldi? I have no real experience with that browser, looking at the version you find online the current is 1.9. Do you use some dev version of the browser?

Windows 10, vivaldi latest snapshot

But now I simulated edit conflict in Opera (win 10) too, and there was two columns for a while, but next page redraw to only one column, so it might be problem in some gadget or user script.

Hmm, I could not reproduce the issue. So yeah looks like it is related to gadgets or scripts. Could also be related to extensions that are not used everywhere.. So again some more input would be helpful if you don't mind :-)

• What's exactly the wiki where the issue is visible?
• Have you tried to reproduce the issue on some other wiki apart from your local one?
• What gadgets do you use?
• When it comes to other custom user scripts my options are of cause limited, but it would be great if you could deactivate your user scripts and try to reproduce it then.

• • cs.wiki
  • i tried it on sk.wiktionary (Vivaldi, Win 10) and got the same problem
• many cs.wiki gadgets + some from other wikis

I tried to search in source code of conflict page which classes are there, but I am not able to see source.

next i tried to disable my global script
https://meta.wikimedia.org/wiki/User:JAn_Dudík/global.js (maybe part remained active? see history)
and got little bit another error - now I have two columns, but one with conflict and one with disabled edit window - all on sk.wiktionary

There are no gadgets on sk.wiktionary, I have enabled only in beta Edit_Review_Improvements and my local scripts
https://sk.wiktionary.org/wiki/Užívateľ:JAn_Dudík/common.js (very old and probably not working)

Hey @JAnD

in T168503 I narrowed the problem down to the wikEd gadget. Could you try the edit conflict with only that code deactivated? And if it then still looks strange could you upload another screenshot?

Thanks!

Change 361827 had a related patch set uploaded (by WMDE-Fisch; owner: WMDE-Fisch):
[mediawiki/extensions/TwoColConflict@master] Temporarily deactivate wikEd on TwoColConfPage

https://gerrit.wikimedia.org/r/361827

For now we deactivate wikEd on the TwoColConflict edit conflict view. See T169098
