pamac-manager crashes on package install

i have updated pamac-* to 10.0.0-2

when i tried installing a package, pamac-manager crashed consistently. the stack traces and terminal dumps are below.

terminal dump;

(pamac-manager:18435): Gdk-ERROR **: 07:23:04.257: The program 'pamac-manager' received an X Window System error. This probably reflects a bug in the program. The error was 'BadImplementation (server does not implement operation)'. (Details: serial 21076 error_code 17 request_code 20 (core protocol) minor_code 0) (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.) Trace/breakpoint trap (core dumped)
