Unsolved Big Sur Pyside2 not showing a widgets
-
Hi friends, since yesterday oficial release of Big Sur , my Pyside2 based app stopped showing any window....
No Any errors ... it runs ... just shows nothing ....
Any idea what to check ?
i created a test app with code from here :
https://doc.qt.io/qtforpython/tutorials/basictutorial/dialog.html
same result : runs but shows nothing...
what am i missing ? -
its really weird but adding :
import matplotlib
import matplotlib.pyplot as pltmatplotlib.use('TkAgg')
at the beginning of the script makes the solution to work ... have no idea why and how matplotlib related... but found it on Stackoverflow... so the problem is not only mine....
hope QT will solve it soon... -

This is good. But for anyone else who comes here with the same problem, it would be helpful if you could paste the link to the stackoverflow post? -

@jeremy_k this bug is in "closed"... does it means there is a solution for that ? not only this strange workaround ?

I'm not sure which workaround is being referenced. The bug report mentions a fix in 5.12.11, as well as gerrit reviews plus commits for 5.12 and 5.15.
