Shouldn't we use locale-aware functions for parsing numbers? (if there's any)

There's no easy way to do this. I can use something like this:

return Number.fromLocaleString(locale, text.match(new RegExp("[" + locale.groupSeparator + "\\d]+")))

But currently, the number of rows is a positive integer in the range [1..20], so we don't need to take into account the locale when parsing it.

Agreed.

Unfortunately, that's not the case. See D24838#570122

Well then I have no idea how to fix it

Yeah, it is a bit tricky problem and affects not only kwin, but other projects as well. @davidedmundson @broulik Have you encountered this problem before in plasma shell? if so, did you come up with a solution that we could re-use here in kwin?
