KiCad 5.1 on 18.04 LTS up todate system
The copy and paste functionality for texts in version 5.1 is utterly broken.
Example for instance in Eeschema
Issue a E, V, U while pointing at any symbol. The system immediately high lights the text which, based on what actually happens, obviously actions a copy command which in turn supers imposes any previously issued copy command within the entire OS. May it be an ordinary ctrl+c/ctrl+v, or the unix/linux build in copy by high light functionality.
Even within Eeschema itself there is no way to copy field texts between symbols other than the automatically high lighted text in the target field itself.
Even attempts to copy some text from outside an open symbol dialogue box (E, V, U) are futile since as soon as the focus returns to the dialogue box KiCad again will automatically high light the text (and commit its value to the copy buffer) where ever the cursor left off. Definitely unwanted behaviour.
This is rather disturbing and extremely annoying to put it mildly.
I reverted back to 5.02 which does the auto high light as well though it is possible to copy and paste text (e.g. special symbols) into an open dialogue box from any system clip board source.
The unix/linux paste by middle mouse click does not work anymore in 5.1!
Reverting back and forth between 5.1 and 5.02 shows that his (mis)-behaviour is consistent.
5.02 limpingly ‘works’ while 5.1 does not.
Apart from the above KiCad is a great tool. Beats eagle any time.
