@philmoz : Do you have any pointers to share for use with all the camera ports so that they can utilize your changes in changeset 1250 and implement automatic menu redraw ?
Just add '#define CAM_DETECT_SCREEN_ERASE 1' to platform_camera.h will enable it.I haven't had any problems on the G12/SX30/IXUS310 and the current test versions for SX130 have it enabled as well.

Patch file on the way.Is it worth just updating all cameras ? This has been a major annoyance for so many people.
extern unsigned int screen_width, screen_height, screen_size;extern void draw_filled_rect( int, int, int, int, int );void vid_bitmap_refresh(){ draw_filled_rect(0, 0, screen_width, screen_height, 0x00) ;}
Once again, i've been fighting with my old friend, RefreshPhysicalScreen() for my G10 port. Here's what I posted 10 months ago :http://chdk.setepontos.com/index.php?topic=5857.0Code: [Select]extern unsigned int screen_width, screen_height, screen_size;extern void draw_filled_rect( int, int, int, int, int );void vid_bitmap_refresh(){ draw_filled_rect(0, 0, screen_width, screen_height, 0x00) ;}Seems like every port fights this one and they are all a little different. The hack I posted in the thread above seems to do the same thing and once I implemented your fix, that might be all that is needed going forward ?
My understanding is that vid_bitmap_refresh is there to tell the firmware to erase and redraw the screen. Using draw_filled_rect will erase the screen; but don't you also lose the Canon OSD?

Using draw_filled_rect will erase the screen; but don't you also lose the Canon OSD?That's what I thought too at first and its probably true. However, from what I can tell, CHDK only uses vid_bitmap_refresh() while in <ALT> mode and you probably don't care about the Canon OSD at that point ?

This has been a major annoyance for so many people.It uses the top leftmost pixel to detect screen erase by setting this to a known value.There is a chance it could cause the menu to constantly erase and redraw if something else changed this value, some CHDK OSD element perhaps (although these are turned off when menus are on).Didn't want to enable something like this globally with no way to test it on a large range of cameras.Phil.
