How to copy and paste a comment

when i copy and paste a line with comments, I miss them!
it seems to have pasted everyting BUT the text inside comments are inexistent, and the frame became empty!
someone could tell me how to solve?

Assume your “line” is a row and you try to copy paste everything. Ctrl+C, then Ctrl+V.

There is this bug report: tdf#108277.
I cannot reproduce anything concerning this issue. (Currently using V5.4.0.2RC)

I also have no problem with Shift+Ctrl+V ‘Comments’ only.

(As many issues in any way related to rendering this one might also depend on ‘Use OpenGL for all rendering’ enabled. Try to disable this option.)
