And after downgrading xserver-xorg-core it worked as before
The program 'xaralx' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
(Details: serial [SOME NUMBER] error_code 11 request_code 148 minor_code 5)
(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 --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
I did a force version in synaptic to the previously installed version.
Same happens with xaralx (Xara Xtreme for Linux):
