Hello,
We recently moved up to SW2018 sp4. I'm finding a few annoying things but the most annoying is that when I show or hide a component in an assembly, it disappears for a moment but comes right back on a hide or comes on for a moment and then disappears again on a show. Only way to make it stick is to do a rebuild. Im hoping this is just a system box that needs to be checked or something silly like that or is this a bug? Nothing can be done with the suspect components in either case but I like to use named display states for operations in a tool and I must constantly rebuild after switching or setting up display states as well. thanks in advance for help.
I'm not aware of any setting that could cause that, and don't remember seeing anyone here reporting similar behavior. It sounds like there might be a problem with your hardware. Have you checked at Hardware & System Requirements | Support | SOLIDWORKS to make sure it's still compatible with SW2018? And have you contacted your VAR about the problem?
