Hello Mr. T,
I tried to reproduce the issue inside a small VM.
I hit an issue when copying something, mostly larger areas, in gimp.
If I started gimp from a terminal I got this message [1].
Maybe you could confirm when you start gimp from a terminal
you see the same message, when the error happens.
Following the advice from the message I get this backtrace [2].
Kind regards,
Bernhard
[1]
The program 'gimp-2.10' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 193066 error_code 3 request_code 18 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 --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.)
