AltGr combination with AZERTY and QWERTZ layouts

[Samobo]

Hello!
I have an issue with the AltGr key while using QWERTZ or AZERTY keyboard layouts:

AZERTY : when I try to write a backtick or a tilde it outputs the number instead
AltGr+7 (2 times) = 7 instead of `` (double backtick)
AltGr+2 (2 times) = 2 instead of ~~ (double tilde)
If I do AltGr+7 one time then type space, it outputs a backtick as expected.

Same for QWERTZ :
Backtick and tilde key combinations two times outputs Ý but one time + space outputs a backtick or a tilde

I have the exact same issue (on AZERTY keyboard, I don't own a qwertz)
as soon as I try to use the ~ character, it writes me another one.
~~ is 2
~/ is ¿
~. is ¾
etc...

In addition, the ~ character stays in the buffer, meaning as soon as I change of text zone and print a letter, it prints right before it.

If you want to fix the issue, simply disable the dead keys (local fix though) following this tutorial https://zauner.nllk.net/post/0014-windows-no-dead-keys/
