[PATCH v15 0/1] MR6075: Add chevron visibility test to check the case of restoring band width to ideal value

[Ilia Docin (＠IDocin)]

I prepared fix https://gitlab.winehq.org/wine/wine/-/commit/b45ad56, that I didn't provide test for, but now I find a way to check it.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:

You should set a non-empty rect here. For example, "SetRect(&g_chevron_rect, 1, 1, 2, 2);". (1,1,1,1) is an empty rectangle. See the implementation of IsRectEmpty().
