I just add Suzanne(Moneky) and then i use the Modifier subdivision. After that the Monkey is gone.
I even install now Blender 3.5 . Totoal Fresh and default setting.
Same Problem.
Everbody can replicate that in under 1 Min. no need to upload.Seems like an bug comes from updates. I even dont use shortcuts. all with mouse movement. See also Video at 5.40 Min. In edit Mode i see an edge cross trough the monkey, look like a fail operation of the software.
try it pleas by yourself Omar, that can help me if u find the reason.
Our does it work with your software and u have Blender 3.5?
