Hi Stefan, I had tested the patches on LS1021A-TWR board using drmlib.
Like set three overlays: root@ls1021atwr:~# ./modetest -P 39:900x100+10+10@RG24 -P 39:200x200+300+0@RG24 -P 39:200x200+400+300@RG24 How did you test the overlays and cursor layer, I mean I see you using x-window like thing in the video.
