The validation pane (the left-side wide window at screen bottom) as displayed
when running CSS HTML Validator under Wine 3 through Wine 5.17.

POSTING this bug report from a CSS HTML Validator user that uses and test CSS
HTML Validator under Wine.

Going back to at least Wine 3, the CSS HTML Validator validation pane has
always displayed correctly until Wine 5.18, when the upgrade from Wine 5.17 to
Wine 5.18 resulted in the validation pane always displaying blank. The
validation pane is located at the bottom of the full CSS HTML Validator window.

See the attached screenshots, I cropped out most of the upper part of the full
CSS HTML Validator window.

The validation pane as displayed when running CSS HTML Validator under Wine
5.18 through Wine 5.22. Text is not visible.

The validation pane as displayed when running CSS HTML Validator under Wine
5.18 through Wine 5.22. Curiously, the messages the validation pane contains
are still present, since clicking within the blank pane causes the invisible
message that was clicked to appear in the small right-side window, which is
normal behavior except for the invisibility in the left-side window. It is as
if the text in the validation pane is displayed in a white font on the white
background.
