interactive plot window not showing under wayland in debug mode for matplotlib=3.9 #1633
Comments
There's specific code in pydevd (the base of debugpy) that likely is out of date with matplotlib: https://github.com/fabioz/PyDev.Debugger/blob/54f8db469c2d8c31635db7cc59a10bc8dab76057/pydevd.py#L695 |
Proposed this fix: fabioz/PyDev.Debugger#289. Curious to know if it solves most of the issues listed here. |
Thank you for the proposed fix, sadly it did not help for me. I could not notice any differences (and I verified that I modified the correct file; raising a ValueError led to the expected result). |
same issue here. any updated guidance on how to fix? I am using python 3.12.1 with up-to-date VS Code for windows, and updated to the latest debugpy 1.8.11 |
There's likely a need to update the matplotlib code that pydevd has. This code here: |
Environment data
VS Code with Python Debugger v2024.8.0
Actual behavior
Try debugging the following code:
If the break point is at
pass
, where Debugger skipped entering the interactive mode, the figure is shown normally.But if there are break points earlier, e.g., add a break point at
plt.plot...
, then debug and go though until we stop atpass
,the figure won't be shown, with a wayland icon/window showing in the taskbar, but an invisible figure window.
Turing on interactive mode manually makes the plot invisible too (set break point at
pass
and debug):Expected behavior
We expect the interactive plot window be shown as a normal window and response to resize/maximize etc.
Steps to reproduce:
mamba create -n 'test' matplotlib=3.9 qt-wayland
QT_QPA_PLATFORM=wayland;xcb
in/etc/environment
orlaunch.json
Additional information:

backend #858 et al.,qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
