Ok, having forgotten about partnerspace, i thought I’d have a play. I don’t use patchmanager, so i thought I’d search this forum and the old one for partnerspace chatter. I found an interesting page here on FSO which uses writes to dconf to enable/disable the space. Application in Partnerspace lossing blur - #5 by sanginteret
I copied their example but with changing the desktop URL’s for 2 of my own. I now have 2 functioning apps. I haven’t yet seen any graphical hiccups, my apps work as they should. One app is landscape only, the other app can be used in both. I’m glad I read this thread. not sure I can help with your problem though, but do thoroughly check out the link above.
No need to use a patch from what I can see, which for me is good news, I always had nothing but grief using it. At least with dconf writes, you can remove them.
