Textures / Shaders issue using Intel Iris XE

Hello ! I'd like to report this graphical issue I've got using my Intel Iris XE laptop on Apex, here are two pictures which will be pretty self-explanatory, but also a textual description.

I've noticed weird artifacts on texture, walls, models when moving, even on characters, sudden colour-changes, and black (2d) squares flickering on some menus. This only started occuring after the mid-season split update which occured a few days ago.
