Flickering Tv-guide and other overlays with EVR enabled - Page 5

nice to see that it has helped others. the problem is, that this is not a valid fix. i just realized that whenever the same image is used more than once within one screen (e.g. when you have not assigned logos to all your TV-stations), all but on instance flickers like crazy.

Added to mantis, targeted for 1.0 RC2 0001192: Flickering Tv-guide and other overlays with EVR enabled - MediaPortal Bugtracker

I cannot imagine anyone using ATI + EVR + Vista HW decoder combo in daily usage when we have this bug, I'm currently using some old Nvidia card on my HTPC as a workaround

Eabin · 2008-04-06, 12:07

btw. there is another way to workaround this problem, a patch for fontengine.dll. when you disable the repainting in FontEngineDrawTexture(....) (i think this was the name of the function), the flickering is gone too, and you can save textures, because it works with packed textures too.
still, this is not a valid fix, as long as noone understands the cause of the problem.

Maybe Bavarian knows? He might be the right person who can give us a valid reason why we are seeing the bug. If not then we just have to resort to some ugly hack that seems to work, but no one has clue how why it works

thanks eabin, tourettes for the feedback.

I'm with you tourette, my wife is not that happy with the flickering right now... So I can't see that it is sufficient for "production use" as it is right now...

eabin: would it be to much work to keep a patched core.dll here in this thread as a workaround for the time being?
It's been a few changes in the core since you put up the last compiled version..

tourettes · 2008-04-06, 22:06

Eabin, was it the following that you advised to be disabled? At least it reduces the flickering (didn't manage to reproduce in quick testing). The side effect this time is that EPG loses channel icons

Code:

if (rectThis.y1 < (rect2.y2))
{
	//needRedraw=true;
}

tourettes · 2008-04-07, 18:16

hmm... doesn't help. //needRedraw=true; is only reducing the frequency when the flickering is happening.

Confirmed, issue occurs with or without EVR.
Currently running system with VMR9 on Vista Home Basic... flickers like crazy!

Still worse during guide! Have we had any progress on this issue?

EDIT: Strangely also... exact same configuration ie: no updates, software changes etc etc, worked without a hitch for 2 days. Only thing the system hadn't done in 2 days was suspend... until last night.

I have one machine as well with exactly these issues:
- AMD 64 Singlecore
- ATI Xpress 1250 with Catalyst 8.3
- Windows MCE
- Flickering with VMR9
- Okay with EVR

One important thing. When you think EVR is working remember to check if you happen to be running on Windows XP as the EVR will be then completely software based
