Snapshot corrupts screen

[ConfusedVorlon]

this is weird, and I suspect there is nothing you can do.

On both the iPhone 6+ and the iPad Pro, my toolbar which shows at the bottom of the screen corrupts when you take a screenshot. On all other simulators, it is fine.

It should look like

I don't see the corruption in the simulator - though I do see snapshot pressing the right-hand button in the toolbar.

Now I'm looking more closely, I'm seeing that other screen elements are undrawn when the snapshot happens. In the example above, the whole bar at the top is gone. In other screenshots - other complete elements are missing.

this only applies on the 6+ and the iPad pro.

Same issue in all simulators:
screenshot should be as following

but snapshot takes:

I'm seeing something similar on 6+ and iPad Retina. It's as if drawing hasn't completed before the snapshot is taken.

I'm seeing this intermittently on various different devices in the simulator (on my last run, it was all devices - see iPhone 5 screenshot below). I noticed, however, that running the simulator from the command line produces the same artifacts. That is, if I run the following, the screenshots in the "output" directory will have the same artifacts:

xcodebuild -project YAWA.xcodeproj \
       -scheme "YAWA iOS UI Tests" \
           -sdk iphonesimulator \
           -destination 'platform=iOS Simulator,name=iPhone 6s,OS=9.1' \
           -derivedDataPath './output' \
           test

So it's clearly not snapshot's doing - it's the simulator. Oddly, I've had some screenshots look ok, then not look ok on the same device (e.g. iPhone 5).

If I run the simulator and hit command-S to generate the screenshot, the resulting screenshot looks fine.

Ok, solved, and this is a duplicate of #249. Run the simulator at 100% scale (hint: hit command-1) and the screenshots are fine.

good spot - thank you.

[cescobaz]

Works for me, thank you

It looks like the Debug -> Optimize Hardware for Window Scale setting is the culprit.

[mihahribar]

Scale solved it for me too.

[robertoferraz]

Scale solved it for me too

[Ged2323]

Awesome scale did it for me too!
