[New-bugs-announce] [issue45496] Tkinter: test_winfo_rgb failure

[E. Paine]

New submission from E. Paine <xepaine13 at gmail.com>:

This issue is to separately address the test_winfo_rgb failure reported by myself in #43139. This issue does not currently affect any of the buildbots.

---

On one computer I am experiencing a problem with the test_winfo_rgb test:

======================================================================
FAIL: test_winfo_rgb (tkinter.test.test_tkinter.test_misc.MiscTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/cpython/Lib/tkinter/test/test_tkinter/test_misc.py", line 213, in test_winfo_rgb
    self.assertEqual(rgb('#4a3c8c'), (0x4a4a, 0x3c3c, 0x8c8c))
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError: Tuples differ: (19016, 15399, 35985) != (19018, 15420, 35980)

First differing element 0:
19016
19018

- (19016, 15399, 35985)
?      ^    ^^^      ^

+ (19018, 15420, 35980)
?      ^    ^^^      ^

I have tested another computer with a very similar setup (Plasma on X11) with exactly the same monitor (both using HDMI) and it passed this test. The only notable difference is one computer is using Intel integrated graphics while the other is Nvidia.
