ipad and shift+tab not working

[Anaxagoras-bc]

I have an ipad m4 pro with magic keyboard, that i'm trying to use as a thin client more or less. Shift+Tab is not working right with wayvnc. Shift+Tab has worked fine in other remote control apps though, as long as wayvnc isn't involved. I'm wondering if this is an ipad thing, wayvnc thing, or combination of the two.

I've tried multiple vnc clients: screens 5, realvnc, jumpdesk, bVNC pro, i'm getting the same behavior on all of them.

using wev here is a good output from when shift+tab works properly:

also interesting is when i run wayvnc in debug mode i get this output only when i hit shift+tab on my ipad

DEBUG: ../wayvnc/src/keyboard.c: 371: send key with level: old mods: 1, new mods: 0

i also injected a shift tab with wtype which also works

wtype -M shift -k Tab -m shift

Is the behaviour the same on git master? I made some changes to keyboard handling recently.

[Anaxagoras-bc]

I just built git master and i'm having the same behavior, although I am getting some better debug logging on git master.

it's saying released, then pressed, i confirmed multiple times. This is from the ipad. I get no debug output when i do shifttab from my macbook, and it works as expected on the macbook...
