Plan 9: 9/pc: swcursor pointer trail
Issue #343
resolved
Sofware cursor on Plan 9 is implemented in 9/pc/screen.c:/^hwdraw/
kernel function.
emu/Plan9/win.c
posts updates to screen image with 'y
' draw function — the Plan 9's memload
— which itself calls to hwdraw
only if the window is partially off screen (in that case, no pointer trail appears).
Plan 9's vncv(1) also had this problem problem until addressed with /n/sources/patch/applied/vncv-curtrail
back in 2013.
Not sure what should be fixed this time though: memload
in Plan 9 or plan9loadimage
in emu.
Cursor trails spoil interactive experience badly.
