Loss of video sync

Evgeniy Kosulnikov

Hi,

Let me try explain what my problem is:

EVM boots and video works fine, but then I launch some QT application and problem starts.

For example, I launch demo browser, which starts correct, but then I choose "Preferenses" from menu and see a strange behavior. It looks like loss of video sync (especially horizontal). So, it happens then application shows a new window or change a tab. In other words, it loses sync when big amount of data is being accessed.

I have C6a8168 EVM  and use u-boot and linux kernel from last PSP release (04.00.02.14).

I don't now how to solve this issue. Thank you for any help.
