when using qt 5.5.1 and qwt multiaxes 6.1 on linux and having 2 Y axis on right side with rotated labels, the Y scale position as well as the curves related to the right scales have a random Y offset error

i only tried the the config in the pics below, didn't try 1 right side scale or no left side scales either

if no rotation is chose, the alignment is correct

plot0x.jpg correct
plot1x.jpg, plot2x.jpg Y offset error
