Comment 0 for bug 1750273

After an update that went live a few days ago, Unity's fractional scaling is misbehaving for some scaling values.

It's something I had already noticed in Unity that shipped in Zesty some time ago. With this update, this now affects Xenial as well.

For scaling values up to 1.38x it behaves as it should, but when the scaling hits the 1.5x mark, the UI elements resize as though I had selected 2x scaling. Text resizes to 1.5x, but the UI itself scales to 2x.

It wasn't like that until this last round of updates to Xenial.
