I'm using a client's mock screens in production code, by painting over the dynamic parts, and repainting them with the dynamic data.
The actual mock is stored in the firmware as is. It then gets drawn, portions painted over like White Out, and then text drawn over that. It all happens before the frame is rendered offscreen so the user never knows, but I do.
It was an extremely cost effective approach because I just used their mocks as is but now I need a shower.

 Whatever works, works. Behind the scenes, stuff. The CodeWitch of OZ does her thing.

I'd like to see your work in action - any chance of a pic ?

It happens  In the current app I'm creating a lot happens before, after and during rendering. What the user see is a smooth opening webpage, some areas are temporally disabled, some tabs appear dynamically, some fields are gradually filed with data. But behind the scenes is boiling barely organized chaos - threads are spawning, joining, waiting for each- other, or completely separate processes are calling back home. I'm not sure I know what I'm doing

Just add "historical growth" to the documentation if you have to hand it out in the future... I have seen / hear that being used as a valid argument for poor design / process the last couple of years. (And I hate it but have to learn to live with it)

I consider that as hitting their spec perfectly! They are probably ecstatic.
Just put in some rendering glitches so that they can point them out to you for correction before you ship.
You probably feel dirty because you copy the entire image to initialize the buffer.(guessing?) Your witch brain is whispering “Why are you copying over all of those regions that did not change?”

I mean, yeah. I feel like the white out approach is what really gets me. It's not so much the technical end, like, performance of it or anything, it's just - it's goofy. It's messy. And it works flawlessly.
Basically this is e-paper, so I have a 2 second refresh cycle. I can take all the time I need, relatively speaking, to draw a frame, so this is one of those instances where I don't care about the inefficiency of it.

Instead of a full white out approach, it sounds like you could go for 25% transparency so they could see more of the beautiful background image.
(Don’t take the bait!)

Pff.. some people are still using Windows 10 or 11 over here.. I am going to leave them all in the dust with my new copy of Windows 98! Muahaha!

3.1 may be better. Less features, less bugs.

Yikes that goes way back. I have a copy on a giant 8" floppy disk somewhere. I thought I had a tape cassette with it CP/M but I forget.

Used telnet with modem and home phone line. Talked to a mainframe via my IBM PC @1200 baud at first if memory serves. I remember getting my first 9600 baud modem. I think I still have it.

Ah, modems... I looked after a national retail chain of close to 400 stores. I developed a MS-DOS batch file, that had a built-in retry mechanism, that dialled into the stores to collect daily sales information using 300 baud dialup modems and generated a report file that the customer's VAX would read. Those were the good old days ... lol

I certainly do not miss worrying about error detection/correction on bytes.

All sounds familiar.
Our main frame was a VAX (later a VAX cluster) running VMS. MS-DOS batch files, couldn't live without them.
Everything is so much different but somehow no so much.
