Cursor colour anomaly when changing character with POKE
Problem
In VGA SCREEN 0, the colour of the cursor should equal the attribute of the underlying character. However, if we change the attribute with POKE, the cursor does not change accordingly.
Steps
Run program below
What happens
Cursor stays grey (COLOR 7)
What was expected
Cursor becomes red (COLOR 4)
Program
10 DEF SEG=&HB800
15 CLS: PRINT"test"
20 LOCATE 1,1,1,0,8
30 FOR I=1 TO 8052 STEP 2
40 POKE I,4
50 NEXT
100 GOTO 100
