LVGL version

v9.1.0-182

What happened?

When testing different Linux display drivers I noticed that the legacy framebuffer one was working, but the DRM/KMS got stuck and didn't render anything besides the initial screen.

Issue seems to be the lv_tick_set_cb call being present on the legacy framebuffer option, but not on the DRM/KMS one.
Issue is not present if that call is done by the user.

For consistency both should have the tick call, or maybe neither..?

How to reproduce?
