Anydesk is unworkable when connecting to the machine with XLibre session instead of XOrg one

Select the version

25.0.0.X

Describe your issue

I'm on CachyOS with NVidia drivers.
I set up XLibre via the script provided for the Arch systems (https://x11libre.net/repo/arch_based/x86_64/README.html), version 25.0.0.12
I seems that I have no problems using it so far generally, but when connecting to the machine with Anydesk, I can successfully initialize the session and see the desktop, but:

• On the client Anydesk machine (which connects to the XLibre machine) I can only see the initial "snapshot" of the desktop screen upon connection, but any updates to the screen are just not happening. Only thing I see is the mouse pointer, I can move it and click it, and it even changes something on the remote machine, but any changes are just not reflected on the Anydesk screen.
• I have 2 screens, when on Anydesk I click on the 2nd screen, i see absolutely nothing, not even some black screen (looks like the program couldn't even fetch anything regarding the 2nd screen).

When I move back to XOrg's packages, Anydesk works again fine.

Steps to reproduce

• Replace the current CachyOS XOrg packages (from the cachyos-extra-v3 repo) with XLibre ones with the provided setup script for Arch systems. Toggle the "Ignore ABI" parameter.
• Run XLibre X11 session and open the current version of Anydesk
• Try to connect to that machine from some other machine

What did you expect?

A working Anydesk session

It was reported that bug absent in master, see #957

[Diatonator]

I'll try to build and test master, if for some reason I'll fail, then I'll wait for the next release and try it

Tested on 25.0.0.13 - the issue persists.

Just for the info how it looks on my end:

Does that happen with other graphics drivers (eg. modesetting), too ?
Can you capture a traffic dump (eg. via xtrace) ?

[Diatonator]

on xtrace /usr/bin/anydesk i get this:

domainname: invalid option -- 'A'
(anydesk:55088): Gtk-WARNING **: 15:58:57.981: Negative content width -2 (allocation 0, extents 1x1) while allocating gadget (node header, owner GtkNotebook)

The second line shows up right after I connect to the computer.

Will try other drivers

Ok, i tried switching to modesetting.
Very strange things started happening to my pc. When my pc finished boot I can only see black screens on my monitors, and the weirdly squished mouse pointer.
I thought that everything is broken and I cannot test Anydesk, but I pressed Alt-F2 and from the opened panel I actually could run and test Anydesk! And its working as intended! Granted I can only seem to be able to open apps via Alt-F2 and the windows are basically floating over the black screen

The same "black screen" thing also happened when I didn't put "Ignore ABI" config file - it tried to switch to modesetting back then too i guess?
