Issue 30756: ttk: GUI tests fail on Ubuntu (original) (raw)

Running the tests over up to date build on Ubuntu 16.04 64-bit.

./python -m test.test_ttk_guionly -v

Sometimes this runs without failure and sometimes it 'hangs' and then produces failures. When it hangs, my computer freezes completely. As you can see, it can run for 8 minutes.

It seems to hang most often on test_idenify in EntryTest.

Here's one set of failures:

====================================================================== FAIL: test_identify (tkinter.test.test_ttk.test_widgets.EntryTest)
