EDIT: I have now found out that this is a feature in the Android Wear OS that reduces risk of image burning on watches with OLED screens. While it makes some watch faces look bad in the sleep mode, I now understand its importance.
When the watch is in sleep mode (display on, but dimmed, slow update rate) the entire watch face position and / or scaling seems to be off. This problem only seems to appear when the face is updated while in the sleep mode, when entering the sleep mode or exiting it the face appears as it should.
How to reproduce:
1. Install on Huawei Watch (Android Wear 188.8.131.521912, Android OS 5.1.1)
2. Set Always-on display mode on the watch
3. Set watch face to e.g. river watch o&b
4. Wait until the watch enters sleep mode
5. Observe as the watch face gets updated while in sleep mode, the whole image shifts a few pixels
6. Wake the watch, the display returns to correct alignment
Please fix this, as it makes the whole app pretty much unusable with watch faces that fill the screen. The offset jump is very visible and gives a cheap look.
