Description Simon Budig 2007-08-31 10:15:41 UTC 
Sometimes the Color picker picks old data. To reproduce:

1. Open an image
2. activate color picker
3. pick some colors (works properly)
4. select e.g. a plugin or colors->invert
5. pick colors again, you get the same picks as in step 3.

If you omit step 3, picking in step 5 will work properly.

Or just pick from another tile to make it work again. The problem
is tile_manager->cached_tile used by read_pixel_data_1(). It doesn't
get ditched when the tile changes so the currently cached tile
still has the old pixels.

Raising priority since this is a bug in our low-level infrastructure.

Fixed in SVN:

2007-08-31  Michael Natterer  <mitch@gimp.org>

	* app/base/tile-manager.c (tile_manager_get): if
	tile_manager->cached_tile is requested for writing, clear the
	cache before giving out the tile. Fixes bug #472170.
