Bug Description

I'm running an up-to-date Ubuntu Focal. I have a standard Spanish keyboard. Under X, if I try to input an accentuated character, such as á or ü, in places like the search field in the overview or when writing a folder name in the app grid, nothing appears. Under Wayland, it fails each time on the first input of an accentuated character, then it works.

I can reproduce the issue on focal but not on groovy. I installed the groovy version of the ibus binaries on focal, but the issue was still present, so this seems not to be an ibus bug.

I can type ü with a German keyboard layout, so it seems to be about dead keys rather than accented letters as such. Furthermore, I can't input e.g. Chinese characters using IBus at all.

I'm amazed and very grateful for how fast this has been fixed, thanks! Will there be an SRU soon shipping this fix?

The fix is already shipping in Ubuntu 20.10 but I don't know when a fix is planned for Ubuntu 20.04. That will be part of the update to mutter 3.36.7.

Thanks, Daniel. Is there any way of encouraging that mutter update in Focal? Or at least of estimating when it will be shipped?

The bug persists with accented characters if the dead key is the first character you type. I mean, open the overview, type "á" and you see just "a". Then type another "á" and it shows correctly. Same if you type "lá", the accent shows correctly because the dead key wasn't the first thing you typed.

That happens to me if the search field is not focused when you start typing, which it seems to not be initially by default. If I first click the search field, also the first letter can be typed using a dead key.

Can you maybe report it as a separate issue, preferably upstream:
