Hello,

Thanks to all those who've worked on PyQtGraph.  I switched to it for a 
real time plotting app as I was bogging down Matplotlib.  
It's easy to use, highly flexible, and fast!

I'm seeing a similar issue as was reported in 2012, where importing 
pyqtgraph stops matplotlib from showing plots:

--------------------my code------------------------------
import matplotlib.pyplot as plt
plt.ion()
plt.show()
plt.plot([1,2,3,4])    # 1) call succeeds, interactive plot window is shown
import pyqtgraph  # 2) after this call the existing plot window from (1) is 
unresponsive
plt.plot([4,3,2,1])    # 3) function succeeds as in (1), but plot window is 
not updated, and remains unresponsive
-----------------------------------------------------------------

I'm running Debian Testing (bookworm) recently updated
Python 3.10.4
pyqtgraph.__version__  = 0.12.4
matplotlib.__version__  = 3.5.1

Regards,
Michael
