Comment 6 for bug 1823165

@Wayne, the unexpected change of font-weight into bold of graphic texts and/or net labels - is randomly occurred as I described. Sometime is normal when I open, but in some other times in opening then unexpectedly changed, and so that I must re-edit all graphic texts and/or net labels to set them to normal weight. The schematic in attachment is originally created, edited, and of course last saved with KiCad V 5.1.

Well, here the last edited schematic example attached with KiCad V 5.1.

Also, you or everyone my check the schematics from https://github.com/kicader/MATRIX-1.4-III/schematics/ whether they with something that may trigger the bug or not with KiCad V 5.1, since the devel' team personals of these schematics also encountered similar trouble in using KiCad V 5.1 that compiled from source under Ubuntu.
