Well, I had a big rant that went something like "blah blah blah... system is the same as last time I played 3 months ago... blah blah... huge input lag in fullscreen but not when windowed..." & then I actually read the thread.
Turning off "Keyboard Manager" in "PowerToys" (a feature I don't use, but was enabled by default when I reinstalled PT a month or so ago) fixed the issues completely.
I'd recommend everyone check to make sure Keyboard Manager isn't enabled, which could potentially fix a lot of people's problems.
Lots of thanks to Anastasios Papargyriou.
Trying to work this out. When I open the Minecraft settings on my iPad Pro, there is an option for "Keyboard & Mouse" with a bunch of settings & keybind options in it, but I cannot get keyboards to work with Minecraft in the way the "Keyboard & Mouse" settings suggest (moving your character & inventory management etc, chat works fine)
My Keyboard Folio does not respond at all while inside Minecraft, with "Full Keyboard Gameplay" on or off.
My Logitech K480 is the same. So is a hardware keyboard plugged in using a USB-C hub.
I'm just trying to understand why there are settings for KB&M when Smart Connector, Bluetooth & USB keyboards do not work. Am I missing something or do the settings built into the game just not work? In which case, why are they there in the first place.
My thoughts are if there are no intentions for hardware keyboards to work, take the options out so people don't get disappointed. Why add settings for a feature, then not make the feature work.
I have been having this issue ever since I got my iPad Pro & was mostly able to get around it by using the linked Secret Settings Mod. That mod has not been updated in a while, & using it now breaks the pause menu. I can access settings, but cannot return to the game while using the Secret Settings mod. In order to get back into the game I have to Save & Quit, then reload the world.
So now I am stuck between a rock & a hard place. I can have the correct safe area, but can't resume the game while going into settings, or I can have a completely borked safe area. (the top end of my safe area is always slightly or extremely off the top of the screen, no matter what setting it is on 0-100)
I understand that there is a way these bug requests get filed & looked at, but to see this & another issue (MCPE-51263) not have any kind of meaningful update in years is a bit disappointing.
