I am also experiencing this issue and on 9.10, apps disappear while they continue to run.
Especially intellij it seems to disappear without fail.
If I select "Always on visible workspace" it does return, however it has on occasion disappeared again after this.
I have ended up simply using the keyboard to switch apps
