Static data/image update on PC wake up

[Sanichka]

Is your feature request related to a problem? If so, please describe the problem.
After I wake up PC screen refreshing only parts with dynamic data(e.g sensors, percents etc) while background image is corrupted.

Describe the feature / solution to your problem you'd like
Add backround and static elements refresh on PC woke up.

Describe alternatives you've considered / and or tested
I haven't dived into code, so unfortunetly my only alternative is to manually restart program each day when I woke up PC.

add display.display_static_images() display.display_static_text() after display.turn_on()

(after line 144 in main,py)

Thanks for investigating, I can confirm this is a bug on the UsbPCMonitor 5inch display model only. When the display is turned off (using its own command) then turned on again, some part of the display will be black instead of the previous bitmap. It seems related to an orientation issue (portrait/landscape) I will implement the workaround from @GaryStar in the next version

I have the same issue on a 3.5 display. But in my case, the USB power is turned off by the motherboard on Sleep. I've added a new variable in config.yaml to control this (also updated configure.py). In case everything is alright on wake from sleep you don't want a full background refresh as it takes a little time and it's not updating the dynamic values while is doing it.

                    if config.CONFIG_DATA["display"].get("REDRAW_BACKGROUND", False):
                        display.display_static_images()
                        display.display_static_text()
