Ok, so here is what I tried :
- New project (empty) : ok
- 1 wall : ok
- adding some walls : ok
- 1 room : ok
- Adding a door or window : this create a hole in the wall and the artifacts appear.
- Removing the door : artifacts are gone
- Starting a new project (empty) and adding a just one 3D object (a table) : artifacts appear (the table is not displayed in 3D view)
- Starting a new project (empty), adding a wall : ok
- Applying a texture to the wall : ok
- adding a 3D object (a ball) near the wall : the object is not diplayed, the artifacts appear / No change to the wall (correctly displayed, with the texture)
Seems to be realted to 3D objects. Also, in the 2D view, some objects are correctly displayed (the basket ball), but some others (babyfoot table) are replaced by geometric shapes
Hope this will help
