Description

Hello all, I have successfully added LVGL 9.2 to my project. I can see what I want to see, but with a jagged/pixelated appearance. Therefore, I am stuck now. Please tell me what I am doing wrong. Is there any link related to anti-aliasing? If yes, then please tell me how to enable it. Please note that the display I am using is a good quality display with no issues in other libraries, and it’s working fine. My color depth is 32 bits and the resolution is 480x800.

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

Renesas RH850/GHS

It should work as it is. Probably it’s a color format misconfiguration somewhere.
Have you set LV_COLOR_DEPTH 32? If so, it should make LVGL work in XRGB8888 (32 bit) format by default.

Are the colors look correct in general? Yellow really should be yellow?
