For instance (Underscores represent displayed tabs), with lines 1/2/3 here:
static const struct toto = {...
__NULL, 0x0323, "ezez" };
Assume my caret is on the third line and going to the second directly to the 'N' (the caret blinks just before the 'N' or covers the 'N' if it is in block mode as I do):
- with printed tabs enabled, the caret would freeze (i.e. can't move it) for one second
- without printed tabs, the cursor would move just fine.
Displaying the tabs is an option I've only recently enabled so I can't say for sure what I noticed was not due to another artefact.
