spurious messages at first plot on qt terminal on Cygwin

[Tatsuro M. <tma...@ya...>]

As far as I remenber, I made the similar question on the phenomena.

After workaround by  by  Enrico Forestieri 
https://sourceforge.net/p/gnuplot/mailman/gnuplot-beta/thread/160...@we.../
I could use qt termninal on Cygwin again.

At first plot in the interactive mode, spurious messages appear.

Terminal type is now 'qt'
gnuplot> plot x
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-user'
libGL error: Windows-DRI extension not available
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
gnuplot> QXcbShmImage: shmget() failed (88: Function not implemented) for size 1394424 (642x543)

>From the second plot the above messages do not appear.

It will be grateful for me is someone will give me suggestions and comments.
