Unity does not highlight the selected text in the bottom panel of the Console window.
I noticed this as well. To illustrate further (as was stated exactly - highlight isn’t working, but selection is), click an error so text is visible at the bottom, if you right-click, you can’t click copy. Then click-drag over a few words to select them, you can’t see anything… but if you right-click again the “copy” option will then be available.
If it helps anyone, to copy for now, you can click the error so the text appears in the bottom part, then click that, then use CTRL-A to “select all” then CTRL-C to copy everything. Then just CTRL-V into notepad/VS/wherever.
You don’t need to even CTRL-A, just click the error and hit CTRL-C and it copies the whole message to clipboard
Unity QA was able to reproduce the issue and a fix is under review already. Thumb up!
