Those BGA ICs (both the main chip and memory) attached to the board with soldering “balls” which are solid. Bending and bowing leads to partial IC separation from the board.
Artifacts are memory errors and could be a result of either memory (gddr) or memory controller (inside the main chip) issue which may very well be a result of the above.
Reflow will usually fix it if the mounting pads are not thorn off the board.
Do not bother with 1050, just replace it.
