G'day all,

I have another slightly wierd problem that does not *seem* to affect anything important.

The menus are slow to refresh, very noticable in frontend set up, where it seems to paint the screen backgound from top to bottom and then fill in the values bottom to top.

I also notice it whan I have an xterm open and cat'ing a large file, the screen is slow to refresh, it seems to be doing a screen full at a time.

Any idea's, I can't find anything in the forum.

I use the 'blue' theme and themepainter=qt, I have noticed when looking at the FE menu that some times a round menu option is duplicated down when the screen scrolls down, but you can't select it it is just visable.

G'day all,

Since no one seemed to know what the issue was, I had a think about the problem and did some more searching and found that it is possibly an issue with QT rendering.

Not much can be done until that is resolved.

google for slow mythtv qt painter render.

It only seems to manifest itself in the setup's anyway, so it is a bit of a non-issue.

Any resolution to this? I just upgraded to R5E50 from R5C1 and have the same problem... R5C1 worked great, but now the UI is sssllllooooowww.

Try changing your theme. I was using Titivillus and the menus were impossibly slow. I changed to MythCenter and the problem disappeared.

Thanks for your response! Unfortunately this didn't work for me. Tried Blue and MythCenter, both are sluggish. I am also seeing some weird painting problems where parts of the screen don't get "wiped" properly when scrolling through menus, etc. The result is that bits of a previous screen hang around when they shouldn't. Something strange going on with Qt?

I saw in this thread
http://www.mysettopbox.tv/phpBB2/viewtopic.php?t=14358&highlight=slow&sid=a3b4640e7ec6e58ff4853fb78fd16329
that some were blaming this problem on heavy RAM usage. I was initially encouraged when I read this because my new install is also experiencing HEAVY RAM usage (all 512 megs of it, actually). I don't think this is the problem, however, as RAM usage is normal right after reboot (~212 megs) and the problem still persists. At some point after reboot my RAM usage climbs to 512, but I'm not sure when. Perhaps a RAM leak or something.

Linux tends to optimize things and use up all available RAM. This is normal and isn't really a problem unless the swap starts to get used. You'll know that if there is unusual disk activity. My problem with Titivillus was related to RAM/Swap over usage...

512M should be enough as long as you aren't running HD. I'm running 256 without any issues at the moment (although I expect in 1 or 2 more releases I will have to add another 256).

Another thing I did when fixing my Titivillus problem was change the resolution to 800x600. I was running 1024x768 and that was causing problems too. Something at 1024x768 was definitely gobbling swap. It would slow down, eventually stop and then reboot because it was out of swap.

You might try a different resolution.

This is an issue specific to the PVR-350 when you are using its s-video output for the hardware accelerated MPEG-2 playback. Or to put it another way, this is *only* a problem if you set up your X configuration to use the PVR-350 as your display via a framebuffer. If you use any other non-PVR-350 output, the problem goes away.

So for that reason, I don't think this issue is related to RAM.

For what its worth, I didn't notice R5D1 having the same kind of slow draw issue that the current release does.

Sounds about right to me. Here's a thought, and this is an off-the-wall suggestion from a lay person so keep that in mind, but I noticed that R5E50 uses a special version of the ivtv X driver specifically made for xorg 7.1. Apparently the regular X driver only supports xorg versions after 7.1. Perhaps this X driver is the problem, or xorg 7.1 itself. Any thoughts on this? unfortunately ivtvdriver.org is down right now so I can't site specifics...

As for changing the resolution, I'm a little foggy on how to do that using the 350's tv-out, so I'll have to dig into that a little when I have time.
