oh my bad, you were not on debug build, release wont show the key events on log, i forgot

is it happens in all apps or only specific apps.

does the issue happens more often with fast typing or simultaneous key presses, or both.

it does happen with every app.

is it happens with Auto capitalization disabled

It happens with auto capitalization enabled and disabled.

Its easier to reproduce when tapping multiple keys at the same time. But happens very frequently when typing fast.

Yep I can confirm facing the same issue

https://github.com/LeanBitLab/LeanType/releases/tag/beta-429-1

is the issue persists

Based on my limited testing for me no

Please merge this into the main release ASAP. This issue is extremely annoying.

you can use the beta release till then, there is no difference between beta and stable version in terms of package name, you can just update from beta to stable to beta no issue just the version number should be higher to update, all the beta and stable have the same version number v4.2.9 so no issue there too

I've switched to the beta version today with the supposed fix but now it writes the first letter which should be capitalized also in lowercase.

I have this happen on the beta version as well but I am struggling to replicate it. It's very infrequent for me.

you can share log, we can find the where the caps words comes from , whether its from personal dictionary/adaptive history/main dictionary/auto caps function
