[ek_ra8d1] The Analytics screen of the widgets demo is flickering with O0 optimization #2

As the tile says

jeremy-baker commented 6 months ago

when vsync_wait is used with lv_display_set_flush_wait_cb(), with low compiler optimisation, vsync_wait() returns before the GLCDC has switched the buffer it is displaying. In this case, vsync_wait() needs to wait for the GLCDC to switch buffers, then wait for a VSYNC interrupt.

I pushed a fix to the project for the flicker issue.
