Thats not particularly the problem here; constrained_layout is a bit of a red herring. `tight_layout` just doesn't know about the big colorbar so ignores it. In the code above `constrained_layout=True`...

Its says `constrained_layout` is to be used instead of `tight_layout` in quite a few places. They are not incompatible per se, just tight_layout cancels out constrained_layout. We could raise a...

Moved to draft. Seems to at least need an Api note, and response to comments above

@tacaswell @learner296 I do think this might be a bit beyond a first-issue, unless someone has struggled with the units system and knows what its history is. But of course...

We'd need a lot more information before we can tell if this is a bug or not. Thanks!

Qt5Agg should automatically detect if the screen dpi is doubled. It calls `window.devicePixelRatio()`. So, maybe your setup is too old to do that (2.2.3 does this, but I guess some...

I actually thinks it’s a pain that the Mac does this rather than just stating its true dpi. The advantage of allowing it to change is dragging between screens w...

Thanks - so far as I can see we already do "Case II" in the blog post about QT above: https://github.com/matplotlib/matplotlib/blob/2125562e0cd6ded113a1de413bb187b762fdf0ae/lib/matplotlib/backends/backend_qt5.py#L127-L130 So its odd that its not working for Qt5,...

I wouldn't recommend editing `rcsetup.py` unless you want to be surprised next time you update matplotlib. Thats what `.matplotlibrc` is for. You shouldn't have to set the dpi to 200...

That makes sense to me. OTOH, we maybe could do a better job of documenting this. I don't think its trivial for a user to know that they need to...
