Hello David, or anyone else affected,
Accepted unity into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/unity/7.4.5+16.04.20171116 in a few
hours, and then in the -proposed repository.
Please help us by testing this new package. See
** Description changed:
- The recently set-hidpi-scale-factor branch provides extremely valuable
- support for hidpi displays, but it does introduce a few easily fixed
- regressions because of the way it anchors scaling too rigidly to
- simulate 140 DPI.

So this patch totally broke my desktop. 1x is way too small 2x is
absurdly huge. 1.5x would be perfect (and was in xenial...)
Any idea how I can fix this for my setup (Thinkpad T460s with a 4k
screen)?

Yes, I had a momentary brain glitch. 1.5x is a better place to put the
sudden jump in size than 2x, so yes, your patch is a good improvement,
and with both patches I think we'll have a good solution.

At this point I think we need both patches. My patch is useful because I
don't see any reason to have unity scaling to 1.99 and gtk scaling to 1.

No it didn't change how it pick the default scaling, it only scales
widgets to make what you described in comment #4 works better.
As you mentioned, GTK+3 does not support 1/8 increments, so if we just
want everything in widgets to scale proportionally to the 1x scale, we
should use integer
I just tried the merge proposal, and it works much less great for me.
The merge proposal changes don't improve the default scaling, which is
the focus of this bug, but it does make it very difficult for users to
choose an in-between scale if they want or need it for accessibility
reasons.
David, can you try [1]?
I just tried it, the patch works great on my 4k monitor.

Thanks for your useful feedback!
So we can either
1. Add an extra knob to choose integer scaling, default to true, or
2. Just use integer scaling altogether.
I subscribed upstream maintainer to see which one is preferable.

The "broken widget rendering" is a manifestation of how GTK3 handles
HiDPI. GTK3 doesn't natively scale at 1/8 increments, so Unity's
scaling is working around that by messing with the size of text and
widgets.
To give you an idea, I'm attaching a screenshot of the same window as
rendered at 1x
Can you attach a screenshot of the "broken widget rendering"? Sounds
like it's a separate issue and we should fix it properly.
In the meantime, I think we can add an extra knob for something like
"integer-scaling", to make scale-factor always round to 8 or 16. But I
doubt Unity upstream would
After thinking through the various cases, I think the cases where
integer scaling can't provide an ideal widget size are also the cases
where user's preferences are going to be split. There is also at least
one usable integer scale for any given dpi.
I did a fair bit of testing to simulate the
Would you like to provide some idea about when it's reasonable to use
integer only scaling, when it's not?
