Some more findings. I used Jolla cautiously throughout weekend but with pretty normal usage (Settings, browser, tweetian, e-maol, tidings, whatismyip, mitäkuuluu logged in but not used) experiencing AFAICT normal battery consumption (bit longer usage periods). Then on Sunday I was in first time chatting using mtäkuuluu (had been just in connected state since 1.0.4.20). App worked fluently, but when I tried to take a picture using Jolla camera, app opened, but sensor image was totally blank, menus and switching between camera/video mode worked normally but no picture and camera button was greyed out. Also I was able to select 'grid' from settings, but it didn't bring it out to camera view. With several retries I once managed to activate front camera preview, but still main camera remained black. Never occured before.

During Sunday I tried to monitor CPU usage with 'crest' and 'top', but for me it seemed normal or at least I didn't spot any process with high cpu constantly. Strange problem, but Jolla seemed quite normal otherwise whole day (maybe battery consumption was bit higher like double to low as other have reported).

In the evening something happened, I double tapped Jolla, in a situation where I quess switching from WLAN to 3G Data might have occured or was occuring. That is I walked into weakest WLAN coverage spot in our house Jolla in side pocket and then taking jolla from pocket and double tapping on screen to read tweetian. After double tap I saw that UI flicking problem reported here. Pixelation seen in 0:23 mark and that started before I even maximized any app from cover page. All apps become closed automatically because of this, and 'top' command reported mitakuuluu eating 94.3 % cpu and 1.8% memory (that is that between 22:33:34 and 22:39:03 'TIME+' column of of mitäkuuluu process went from 1:18:96->6:40:38). As a comparison lipstick process that was also under 12.4% load durig the event its TIME+ column went from 0:09.84 to 0:28.53 proving that loads were constantly high.

I think that runaway process was _background server_ process of mitäkuuluu app (seen as 'harbour-mitakuuluu' in process list) since that process remained there even I successfully opened mitäkuuluu UI and connected to whatssapp service and then disconnected and quitted app.
What I am not saying is that what was the root cause of the problems, hanging mitäkuuluu bacground process might just as well be the victim of badly behaving connection switcher of Sailfish and so on.

After reboot everything went back normal and battery went overnight from 100%->96% during 6h.

Then on Sunday I was in at first time chatting using mtäkuuluu (had been just in connected state since 1.0.4.20). App worked fluently, but when I tried at the same time to take a picture using Jolla camera, app opened, but sensor image was totally blank, menus and switching between camera/video mode worked normally but no picture and camera button was greyed out. Also I was able to select 'grid' from settings, but it didn't bring it out to camera view. With several retries I once managed to activate front camera preview, but still main camera remained black. In video mode I saw tiny yellow warning triangle in focus frame. Camera problems Never occured occurred before.
