 Fwd from tsimonq2: File a block-proposed bug (or whatever) on Mesa.
 @mitya57 ^^^
 Maybe let's remove qtbase task from that bug?
 qtbase was unintended casualty
 @mitya57, problem is, the bugfix is in Qt
 or at least last I saw
 could add the tag back once qtbase is through. one of thsoe situations where no one way is perfect
 or take off qtbase for now, and add it back once you are landing a fixed qtbase?
 if it even needs to go back
 https://codereview.qt-project.org/220412 might be an upstream fix for this
 So let's wait a bit more, if that fix is accepted then cherry-pick it, otherwise add the bug tag back
 that was the idea. did not realise mesa was going to be quite so blocked on it's own issues the other day, so it was important to halt that
