How to reproduce:
1. Open user-supplied project
2. Load scene "main"
3. Build & run
4. Select a non-native resolution (tested on 1024x768 and 1280x768 using 1920x1080 screen)
5. Click "Play!"

Expected result: Text should be smooth when the project is built.
Actual result: Text has artifacts (is choppy) when built.

Reproducible on: 2017.2.0b3, 2017.2.0b2, 2017.1.0f3, 2017.1.0b4, 2017.1.0a6
No reproducible on: 5.6.2p4, 5.6.2p3, 5.6.0f1, 5.5.2p2

Regression introduced somewhere between 2017.1.0a1 and 2017.1.0a6 (could not test 2017.1.0a1 through 2017.1.0a5 because of either crashes or black screen when running the build)

Note: Artifacts appear even on the mandatory Unity splash screen (free users).

Fixed in: 2017.2.0f2, 2017.3.0b1
