.25 popup down menu redraws and flickers several times

Hi,

I recently upgraded to .25-fixes from .24 and noticed when hitting the
popup menu button while watching a recording, it draws the menu on the
screen several times. This appears as flickering of the menu and
sometimes worse. I ended up rolling back to .24. Has anyone else seen
this behavior?

Thanks,
R

Did you try a different theme? This would have been the first thing I
had tried before reverting to 0.24. Which one did you use anyway? I'm
using Arclight and have no problems at all.

I've noticed this after I upgraded my frontend to a mac mini with a nvidia 320M.

This was on 0.24...
I figured it was more to do with the graphic card than anything else

I would guess it has to do with the various fixes for channel changing
in live TV. I think there are queries going on about whether the
channel is currently tunable, and that is happening in the main event
loop. If the query/queries take longer than the frame interval, there
is stuttering.

Sorry, ignore this. It was meant for a different thread.

I see it on Arclight, you need to look for it, as its small issues here
and there. e.g. in the watch recordings screen, switch between the panes
and notice that the icons for widescreen/surround/etc. come and go.
I could not find a pattern with the fanart being there/missing or
anything else. Its not missing vsync as its sometimes a full second or
two until the icons get painted (if at all) so it looks like some
drawing order / overpaint issue.

Regards,
Karl

I normally use the mythcenter-wide theme. Right after upgrading it
switched to the Terra theme. I then switched it back to
mythcenter-wide. I went back to 0.24 because I had a small window of
time in which to try out the newest version. My window is dependent on
the wife factor and also on the number of upcoming recordings.

Other folks are mentioning flickering when changing channels. On the
surface it may not be related, but if the code used to overlay windows
on the screen is the same, perhaps it is? - Just thinking out loud.

I've suffered this recently as I'm in the middle of a migration from one OS to
another. Couldn't understand what had happened at first.

Turns out this is a red flag that you're not using the settings that you
originally configured in the database, and in my case this was due to an
inadvertant change in the hostname.

In my case I changed *one* word in my default network configuration, to remove a
DHCP/hotplug bug in Debian, and my hostname spontaneously changed from
'ruby.local' to 'ruby.example.com' on the next boot. I have no idea why. Lo and
behold, half my settings disappeared.

To Mike Dean et al: I changed *nothing* in my mythtv config to cause this. I
have exactly one copy of mysql.txt and config.xml with symlinks to them from
everywhere required. Nevertheless, mythbackend startup decided that I was
operating a new slave back end.

Right, unless you specify a "LocalHostName" override (which we plan to
change to a much better name--and, possibly, completely dissociate from
host names), we use the host name, as returned by the hostname
application (we use code similar to that used by it) as your default
machine identifier. Since all settings are keyed off of the machine
identifier, you end up losing your settings and going with defaults.

That said, if someone can identify the setting that's causing the
flickering, we can probably fix it--either fix the flickering or at
least fix the defaults. It's likely some setting in the playback
profile group you get--though some have said that changing playback
profile groups doesn't help...
