VMWare Window Crash: Info on libx11-6 and recent kernel changes with 6.19.11 - fix included

[mmattel]

Debian 13 (trixie) using Backport (applies to other distros too),
VMWare 17.6.4 (applies also to more recent versions 25h.x)

I updated the kernel from 6.19.10 to 6.19.11 and when starting a VM, shortly after the VMWare window crashed, the VMs continued to run. journalctl -f showed the following:

The program 'vmware' received an X Window System error.
                                           This probably reflects a bug in the program.
                                           The error was 'BadValue (integer parameter out of range for operation)'.
                                             (Details: serial 10060 error_code 2 request_code 135 (XKEYBOARD) minor_code 8)
                                             (Note to programmers: normally, X errors are reported asynchronously;
                                              that is, you will receive the error a while after causing it.
                                              To debug your program, run it with the GDK_SYNCHRONIZE environment
                                              variable to change this behavior. You can then get a meaningful
                                              backtrace from your debugger if you break on the gdk_x_error() function.)

After searching around, I found that the "culprit" is the current libx11-6 library with installed version 2:1.8.12. A fix has been provided with version 2:1.8.13 which is at the time of writing in testing stage (package forky), see: https://packages.debian.org/forky/libx11-6

After manually downloading the libraries and updating them with:
sudo dpkg -i libx11-6_1.8.13-1_amd64.deb,
sudo dpkg -i libx11-xcb1_1.8.13-1_amd64.deb
I do not have any more issues with crashing VMWare windows.
The filenames depend on your architecture.

If you want to revert, just download the former version (1.8.12-1) and install them as shown above.

@Hyphaed maybe you find a way how this info could be noted in your build output helping desperate users fixing it.
BTW, get back healthy soon, all the best !
