Writing direction in text fields changes to right to left

[b00nish]

Hi

I'm using Vivaldi on Linux for years now but a couple of weeks ago I started to notice a strange behaviour that I never experienced before:

Sometimes when I type something into a text field (for example the search field on Google but also other text fields on other websites) it writes rigt-to-left instead of left-to-right.
This happens by itself without any known reason.

If I right-click the text field and go to the writing direction, left-to-right will be ticked even if in fact it's right-to-left that is "happening". Ticking right-to-left and then back to left-to-right will usually fix the issue. Until it happens again a bit later.

As far as I can see the issue only happens with text fields that I already have written something before. So if I first write something into an empty text field it never seems to happen. But if I later write something new in a text field that already contains something that I wrote in earlier, it sometimes happens - but not always.

I experience this like twice a day on average for the last few weeks. Had about two Vivaldi updates since then that didn't fix the issue. Currently I am on 4.0.2312.38.
The issue is only in Vivaldi, not in any other software (including Firefox browser) that I'm also using.

I use Kubuntu 20.04 with newest patches. Language setting in Vivaldi is German, Keyboard Setting in the system is "German (Switzerland)"

@b00nish Hi, I've never seen this. Are you able to find a way to trigger this behaviour consistently?

My guess is an extension might be causing this. Please try the troubleshooting steps first:

Try in a clean profile, change language to English, restart, see if problem goes away. Then change back to German/Swiss and see if it comes back, if so its a language setting problem.
