I think it's related to my configurations . for example

 Screen 0: minimum 8 x 8, current 3520 x 1080, maximum 32767 x 32767 

. is this currect ?

thanks for your help in advance.

Re: My two monitors appearing as one widescreen [WORKAROUND]

Afaik "Screen 0" means that both your monitors connected to same GPU
I think it's electron fault, that's why discord and skype can't find correct monitors

is web.skype.com an electron project? if it is you are probably right.
thanks. is there any workaround to fix this behavior temporarily?

UPDATE:

based on your reply I found this news:

Xakep_SDK was right. this is a chromium bug. I found a workaround for now and shared it for others facing a similar issue:
