OK, with CHDK 1.3 these are my results:

Free Memory Without Zebra Enabled:

1) just after startup, in playback mode: 1471264
2) after switching to rec: 1471264
3) after pressing and releasing half press once: 1471264
4) after shooting once: 1471264
5) after shooting twice: 1471264

Free Memory With Zebra Enabled:

1) just after startup, in playback mode: 1237576
2) after switching to rec: 1237576
3) after pressing and releasing half press once: 1237576
4) after shooting once: 1237576
5) after shooting twice: 1237576

NOTE: I noticed that my memory dropped as soon as there were images to display, because I repeated procedure again without zebra and got same results as with zebra, when I deleted photos, it went back to 1471264 bytes, which I believe is normal since it has to load thumbnails for display

I also want to say that the jog dial (the one in the back not the mode dial) sometimes seems to be unresponsive, is this a possibility with CHDK? sometimes it's perfectly fine and others I have to dial a lot for it to respond. This did happen also with CHDK stable 1.3 but forgot to mention....
Does this affect the canon UI, the CHDK menus, or both?

Regarding the crash, the 1.3 notes.txt has says
Quote
#define CAM_ZEBRA_NOBUF 1 used to prevent crash, see: http://chdk.setepontos.com/index.php?topic=10984.msg112340#msg112340
It looks like no further progress was made on this issue, and the define was not added in the trunk. edit: not correct, see later posts.

I've attached a 1.4 build with this define set. To me, the symptoms like look some kind of memory corruption...


edit:
Oops, I attached the wrong build

edit 2:
Correct build attached, previous one didn't actually have the define set  :-[

Just tested it, it did take a shot at first or two, then crashed. Same when checking memory after half press.

Now memory when powering on on play is 1279352 bytes both zebra enabled or disabled.

About the jogwheel. I disabled CHDK to use camera normally and seems to be more responsive, I'll keep an eye on that....

Will just extracting and overwriting the whole structure in card work? Nothing will become corrupt?

Yes, that should be fine.

Looking further, the zebra bug was supposedly fixed trunk r4134, referencing this post http://chdk.setepontos.com/index.php?topic=10984.msg120213#msg120213

Still worth trying 1.4 with the define set.

OK, it's working! The only issue is that it draws sometimes all over the screen blinking like it does with 1.3, but I can see the overexposed highlights, no crashes and memory seems to be stable...  :D

Well I'm off to sleep for now! Any further testing just let me know and I'll get back to you tomorrow. I'll keep an eye open on the rest and see what else pops up...

I want to thank you so much for you hard work...

Cheers! :)
