What MCU/Processor/Board and compiler are you using?
Allwinner t113s4 running debian trixie on latest mainline kernel, with an rgb->hdmi bridge.
What LVGL version are you using?
I tried multiple, 9.0-current master
What do you want to achieve?
GitHub - lvgl/lv_port_linux: LVGL configured to work with a standard Linux framebuffer running smoothly at 30 or better 60 fps, with reasonable cpu overhead.
What have you tried so far?
Trying both fbdev and drm backend.
Code to reproduce
No edits
Screenshot and/or video
Nothing special, it runs and looks as expected but cpu is often at 100% and especially on scrolling fps drops to around 3. Attaching “systrace”
