[Kwintv] Heavy flickery and noise when switching viewmode in qtvision

[Florian Evers]

Hi,

when I switch between the different viewmodes in qtvision
(normal, full screen, tv mode), there is a lot of flickery on the TV
window and a lot of "noise-crackling" mixed to the sound.

I started qtvision on the console, to see the debug prints.
For every "flickery" in compination with a crackling noise, a new line appears:

qtvision: SaverControl: KDE screensaver successfully disabled.

... this happened when switching from "full screen" to "normal view", all events
together happened in a timespan of one second. After this, the TV output was ok.

I dumped all debug messages to a logfile by typing "qtvision 2> logfile.txt".
I started qtvision and simply rotated through the view modes, and finally shut down
qtvision. [See Attachment]

Hope it helps ;-)


Keep on this great work! :-)
