Xperia u landscape screen problem

[raduelvis]

Hello,im facing a problem with my xperia u after upgrading to ics (curent firmware 6.1.1.b.1.100) when turning in landscape mode the part of the screen neer the sony logo refuse to update normaly with the entire screen and produce tearing effect,and also vertical lines,this problem persist on all ics firmwares b.1.54 or b.1.8.In vertical mode phone reacts normaly and there is no problem with screen(checked with flash update screen),im also 100% positive that this problem dont exist in any gingerbread android version on this phone,i requst any help/info possible to fix this,i dont wanth to rollback to 2.3.7 because ics gave to my phone more stability and processing power,thank you and sorry for my english

is this while on an app ? or are you using an app to force landscape on the home launcher?

it dosent ocure while playng heavy games like most wanted or deadtriger but it ocure when seeing a video on youtube in landscape mode (portrait dosent have any problems) or when i slide in the browser in landscape mode the screen part neer sony logo produce form time to time tearing effect like tearing a paper

The app might be a bit too heavy, try to clear cache on both apps and see if that help

That's quite interesting, perhaps a Sony moderator should reply, and I'm certain that you have try the basic, such as repair your phone and/or flash different firmwares?

tryed with SUS to repair but it didnt helped, also on b.1.54 i was facing same problem,its quite funny cuz on 2.3.7 didnt had any of those problems,phone is still locked with stock firmware,never tryed to flash a costum rom cuz will ruin my warranty,and who knows maybe i'll need that soon ^^ thank you for your help and im looking out for a respone from one of the sonny staff members
