Just think how much you will brighten the solstice by finding and fixing one of our tests! Or, if you're a south hemispherean, it's way too hot to go out, so you should stay in and fix a test.
A curated list test failures on our static Windows VMs and on a first Linux machine is here: https://www.winehq.org/~jwhite/latest.html
We've made some good progress lately; we are down to 10 failures total on the Linux box, only 3 of which are consistent. Windows failures are way down; although we still have a nice bunch of Windows 8 and 10 failures left.
In fact, the thing we have the *most* of are sporadic Windows 10 failures - everyone's favorite!
Alexandre assures me that test fixes are welcome during code freeze, so bring some solstice joy and fix those tests!
Cheers,
Jeremy
