      Description

      The eglfs_kms backend for EGLFS seems to be limited to double buffering and there is reason to believe that with Qt Quick more than 2 buffers should be created for optimal UI smoothness.

      It seems that the eglfs_kms plugin chooses to wait/block, rather than querying for, and using, additional buffers when they are available.
