The oven trick really won’t fix the root issue only buy you some time!
-
Most of the time you’ve not even getting the chip hot enough to effect the solder joints. This gets into what has really failed one of the tantalum caps (most likely) or if you have a fractured solder joint or cold solder joint. These both need flux to fix and getting off of the Tin based solder Apple uses. While I agree Lead solder is bad! ITs more an issue of where its’ used. Hot running components like CPU or GPU chips should have a leaded solder a few percents of Lead won’t be a big deal for these.

Frankly, I’m thinking you may have more of an issue with the Switching and MUX logic which you can see here on the left in this block diagram. This might only need a a new tantalum cap! Vs having a bad GPU.
