Display´s driver restriction and rendering


What MCU/Processor/Board and compiler are you using?

GR551x MCU+ RM68090 LCD Controller

What LVGL version are you using?


What do you want to achieve?

correct rendering of widgets

What have you tried so far?

I’m trying to run LVGL on my board but so far it’s not working well.
The thing is that the display used has strange limitation that is violated when rendering LVGL.
I have no idea how this can be fixed in a correct way. I understand that if you use “pixel-by-pixel rendering” then this problem will not exist, however, in this case, the UI will be unacceptably slow.
Please give your advice on how to make LVGL put widgets with my display vendor limitation (attached imgs).
Thanks in advance!
