Lima: very poor performance on sun7i A20

System information

  • OS: Gentoo
  • Platform: Olinuxino A20 Lime2
  • GPU: Mali 400
  • Kernel version: drm-misc-next 38d6fd406aaa30a1381074b083776cd280479e22
  • Mesa version: git master 22554e1f
  • Xserver version (if applicable): 1.20.99.1 and Wayland
    • Configured as told here: https://gitlab.freedesktop.org/lima/web
  • Desktop manager and compositor: dwm Sway

Describe the issue

  • X:
    • Mouse movement is slugglish, cursor becomes invisible when moving
    • slow response
    • urxvt exhibit character per character refreshes
    • only about 45fps in glxgears, cursor flashes if placed on glxgears window
    • Interestingly, settting AccelMethod to none gives me smooth mouse movement and about 20fps in glxgears.
    • mpv with soft decode drops hundreds of frame
  • Sway
    • Had to set WLR_NO_HARDWARE_CURSORS=1
    • slow response but better than X
    • Cursor skipping and movement is sluggish
    • mpv with soft decode drops hundreds of frame

Xorg.0.log I can provide more logs if needed.
