Bug report

The following code example uses the RectangleSelector widget, so that we should see a continuously updated rectangular patch over the plot. However, nothing can be seen, unless we set useblit=False.

Code for reproduction

#!/usr/bin/env python3

import matplotlib
from matplotlib.widgets import RectangleSelector

if __name__ == '__main__':
    matplotlib.use('wxagg')
    import matplotlib.pyplot as plt
    figure = plt.figure()
    rect = RectangleSelector(figure.gca(), (lambda e1, e2: print(e1, e2)), useblit=True)
    plt.show()

Matplotlib version

  • Operating system: ubuntu 17.10
  • Matplotlib version: 2.2.2
  • Matplotlib backend: wxagg
  • Python version: 3.6.3
  • Other libraries: wxpython 4.0.1

Everything was installed from virtualenv + pip.

Could you check with latest wxpython 4.0.2 and matplotlib git version? It appears to work here.

Works for me with wx 4.0.1 and matplotlib 2.2.2 or git HEAD.

I've tried with wxpython 4.0.3 and both matplotlib 2.2.3 and matplotlib git head. I'm still seeing the bug. Perhaps it has something to do with ubuntu.

OK, I will have a look and start a Wayland compatible implementation. I can start earliest next week, though.

@tavin : as a workaround, you may select X from the login screen: https://askubuntu.com/questions/961304/how-do-you-switch-from-wayland-back-to-xorg-in-ubuntu-17-10

@tavin : I have just submitted a PR #11944 to fix the Wayland issues. Maybe you can check whether this fixes your problems.

This issue has been marked "inactive" because it has been 365 days since the last comment. If this issue is still present in recent Matplotlib releases, or the feature request is still wanted, please leave a comment and this label will be removed. If there are no updates in another 30 days, this issue will be automatically closed, but you are free to re-open or create a new issue if needed. We value issue reports, and this procedure is meant to help us resurface and prioritize issues that have not been addressed yet, not make them disappear. Thanks for your help!
