OK, so, the situation goes like this. When I start IM+ pro 5.0.2, as autoconnect bug will be fixed in next version, IM+ won't connect to my wlm service. So, at that time i have IM+ turned on but not connected to wlm.
In that case, I go to settings, and I think I don't need to change anything in settings, just enter and than exit to main screen (contacts, chat... it's the same). And than I go to connect to my wlm service and because of autoconnect bug I have to click disconnect all and than connect all. After few second IM+ connects to my wlm service and then if I go to chat or contacts section it's a gray bubble background instead of just white.
I think that I can reproduce this situation every time if I fallow this steps. But at this moment my phone is at my gf so I can't 100% confirm this.
This background is also in chat section. And if I have one chat open I have 1 gray bubble under that chat session if I have 2 chats open I have two gray bubbles, one behind each chat....
But if I go into chat, so I can write messages to my contact, there isn't that bubble, there I have normal white background if that's what you meant by your question. Because of the previously mentioned reason I can't send you ss at this moment but everything is normal there so there's no need for ss.
My opinion is that that background could not create itself from nothing, someone had to create it. And you now very well your program and if you didn't put that picture in your program (maybe for some other function), than your program is taking that picture from some other location on phone. Your program isn't application that can create picture by it's own will so that picture has to exist somewhere in memory of my phone. The question is: why is your program using picture that belongs to some other program on my phone and why exactly that one? I must also say that I didn't see any program using that picture so I don't know to which program it belongs.
But this isn't such a big problem coz I won't go to settings each time especially when you fix that autoconnect bug. In that case I'll be online on wlm as soon as I start IM+ and then I can go to settings without this problem will happen. But I mentioned it so you can know about it if someone else asks you about it.
And if you forgot my configuration and you need it, it's: Samsung GT-I5800 / Kyrillos 9.3 ROM (android 2.2) / G3MOD 2.2.2 kernel / with turned on compcache and v6_supercharger script. Titanium shows that I have 111 apps and if you need which one I can post you a list.
Also feel free to ask any other question about my configuration if you need it.
