Intermittent exception thrown trying to update ImageItem #3138
Description
I am seeing the following stacktrace with pyqqgraph (latest version).
Forgive me for not posting the code, I can't get an MRE to reproduce it right now.
It happens intermittently when setting an image for ImageItem.
Only happens when autoDownsample=True
Exception caught:
Type: <class 'IndexError'>
Value: index 207 is out of bounds for axis 0 with size 200
Traceback:
