I don’t know which version fixed it but I have not ran into it for awhile. I loaded the world that the recordings were made on and attempted to reproduce it on 1.20.13 and was unable. I assume it is fixed.
iPad Pro (11-inch) (4th generation) [model number MP5E3LL/A]
Keyboard: Magic Keyboard with Numeric Keypad (Bluetooth)
Mouse: Basilisk C HyperSpeed (Bluetooth)
iPadOS 16.1.1
I’m glad somebody managed to capture a video on this. It happens to me a lot and yesterday I died to a slime, of all things, because I couldn’t use the attack button since it would zoom instead. This isn’t limited to mouse as touching the screen will also zoom when it is in this state.
it clears sometimes if you switch away from the app and back which prevented me from hitting record each time. It also occurred on 1.19.40 and others - I started seeing it as far as I recall only after iPadOS 16 update.
I see a similar report in recent comments on ticket MCPE-51263 w/recording demonstration. There is mention of running into this issue on terraria forum also
*REPORTED* - iPad keyboard and mouse glitch IPadOS 16.1 Terraria Community Forums with mention of it affecting them in Minecraft and suggesting it is related to ESC key on keyboard being used.
Reproduced the problem on 1.20.15
This behavior seems to be tied to usage of the Esc key on keyboard to close inventories and get to pause menu. If you avoid using the Esc key, i.e. exclusively using a bound key like ‘C’ or ‘E’ to open and close inventory or using touch screen to try to get to the pause screen the problem does not occur.
In my short test, using Esc to exit inventories did not quickly reproduce the problem so needs further testing; however, hitting escape to get to the pause screen first gets you into a mode where trying to click, seems to ‘zoom in’ on the screen instead of clicking the targeted buttons, but switching to touch screen to click the button to get back into the game, the mouse was then behaving like the attached video from before.
