This has been driving me crazy.
I’m using a Pixel with GrapheneOS and the FUTO Keyboard.
Slight workaround for everyone on Android: Click the keyboard selector at the bottom right of your screen and just select the already active keyboard. This will temporarily fix it until you start to type up a different comment.
hmm doesn’t seem to work for me.
Only thing that works is to manually re-select the keyboard among my keyboard selection/input method.
