Reasons for FreePicture to cause "RenderBadPicture"?

[Clemens Eisserer]

Hi,

I have some code which causes "RenderBadPicture" errors from time to
time, and I have troubles finding the cause.

I have inserted some debug code and switched to synchronous mode,
however I don't get an idea whats going wrong.
Some pictures don't seem to cause problem, whereas other pictures
cause a single or even multiple errors although only freed once in
what seems to be a free call to free a completly different picture
like FreePicture(4c00184) which results in an error for picture
4c00189.

Any ideas whats going wrong?

If the "parent" drawable the Picture belongs to (e.g. a window or
picture) is freed, are all corresponding Pictures freed automatically
and cause a RenderBadPicture when a FreePicture is later attempt?

Thank you in advance, Clemens
