Short description

I have recently updated from PyQtGraph version 0.13.3 to version 0.13.7. Users of the software I write have noticed that the plots using version 0.13.7 now have vertical/lines for all minor ticks instead of only major ticks as in version 0.13.3. Would it be possible to have the option to hide the grid on minor ticks ?

Code to reproduce

import pyqtgraph as pg
from PyQt5.QtGui import QGuiApplication

# Create window
win = pg.GraphicsLayoutWidget(show=True)
win.setWindowTitle('pyqtgraph example: Scrolling Plots')

# Add plot
axis = win.addPlot(1, 1, pen=pg.mkPen(color='#000000'))

# Show grid
axis.showGrid(x=True, y=True)

QGuiApplication.exec_()
