OS_SpriteOp simple PutSprite wanders off end of sprite data
| Reported by: | Stuart Swales (8827) | Severity: | Normal |
| Part: | RISC OS: General | Release: | |
| Milestone: | Status | Open |
Details by Stuart Swales (8827):
And if the end of sprite data is the end of a page, that’s all folks…
Please try the attached, which loads a sprite file just below HIMEM and tries to plot it to screen (which should be the same depth as the test sprite, in this case, 16M colours).

This will affect rendering of (some) sprites that are immediately adjacent to the end of the Wimp Sprite Pool (though it’s taken a long time for this to surface in a reproducible manner). Perhaps on systems with oozles of RAM an extra 4KB guard page could be maintained on that?
