#37644: tcl/tk 8.6 breaks spectrum rendering in ccpnmr
-----------------------+--------------------------------
 Reporter:  howarth@…  |      Owner:  macports-tickets@…
     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.1.2
 Keywords:             |       Port:  ccpnmr
-----------------------+--------------------------------
 The migration to tcl/tk 8.6 breaks the ccpnmr so that it can no longer
 render NMR spectra without crashing.[[BR]]
 Confirmed that reverting tcl/tk to 8.5.13 and rebuilding py27-tkinter
 against this version restores full functionality.[[BR]]
 The rendering under tcl/tk 8.6 fails with...[[BR]]
 [[BR]]
 >>> Spectrum successfully opened[[BR]]
 finished opening spectrum Expt_1 ghnhb_3D[[BR]]
 X Error of failed request:  BadDrawable (invalid Pixmap or Window
 parameter)[[BR]]
   Major opcode of failed request:  70 (X_PolyFillRectangle)[[BR]]
   Resource id in failed request:  0x601811[[BR]]
   Serial number of failed request:  47218[[BR]]
   Current serial number in output stream:  47221[[BR]]
 [[BR]]
 IMHO, the migration to tcl/tk 8.6 was premature and should be reverted
 until tcl/tk 8.6.1 is released.[[BR]]
 It is unclear if the defect lies in tcl/tk or _tkinter of py27-tkinter.
