@jrast Thanks so much for your testing. Can you confirm the scrolling problem does not occur with 5.12 with
pyqtwebengineinstalled, and also does not occur with 5.11 and it not installed, to confirm the problem is linked to
pyqtwebengine? I've experienced a problem myself with Qt 5.9 that involves Spyder crashing if I scrolled fast and held
Ctrlto zoom in and out. It was also very intermittent, in that sometimes it was triggered right away, while sometimes it took a while to occur.
PyQtWebEngineinstalled again: Scrolling seems to work. However, I was playing around in the same environment as yesterday and updating PyQt5 from 5.10. to 5.12. did not work as expected. After
pip install -U "PyQt5>=5.12"I was not able to start spyder (ModuleNotFoundError: No module named PyQt5.QtWebKitWidgets ...). I uninstalled PyQt5, PyQt5-Sip and PyQtWebEngine and installed them again, then spyder was able to start.
Spyder==3.3.3, as long as the Spyder 2 Icons are used.
pip install "PyQt5==5.12.*" PyQtWebEngine "Spyder==4.0.0.b1", Spyder startup works, autocompletion works, help viewer works.
updating PyQt5 from 5.10. to 5.12. did not work as expected.
Thanks. This would have to be due to a random issue with
pip; nothing we can do about that of course. Its why we recommend
conda (or sticking with the tested WinPython versions) for users who aren't as experienced as yourself who can resolve those types of issues on their own.
PyQt5==5.11.* does not include the QtWebKitWidgets, so Spyder will not launch.
Are you sure about this? As far as were aware, the split happened in Qt 5.12, which is why the PyQtWebEngine package is compatible only with it. Perhaps what may have happened is the exact same thing is when you upgraded to 5.10; something went wrong with
pip and it didn't install the new version properly so you got the error.
