Screen blanks out

I have been noticing a problem whhich has started to happen recently. I noticed it with 16.9.1 drivers and also after I installed 16.9.2
What happens is that the screen picture disappears for a few milliseconds. It is not possible to time this but it is quite short, less than a second I think.
The problems once it starts to happens continues to happen periodically, no constant time. Sometimes you get two instances in a minute but then not for 15 minutes so it is quite random.
I do use the browsers quite a bit both IE and Firefox.
I was wondering if anyone else has this problem?

I am not a gamer so my GPU does not get trashed.
Typical GPU stats

I have also set the fan to target to 70C

Any BBC transmission at 1080i fails when DXVA enabled.

H.264 interlaced content cannot be handled by AMD drivers correctly when turning on DXVA.

Re: RX480 DXVA H.264 not working.
Frank Vella Decahertz
A reponse from DVBviewer forum:
I think AMD and Nvidia have different issues.
AMD => interlaced H.264 with new RX 4x0 cards and / or new drivers
Nvidia (and Others) => stream errors with "bad" error handling
seems to indicate the problem is interlaced content.
From my tests
Astra Demo 2160p works fine
BBC HD 1080i does not work.
I don't have 2160i content so cannot verify.
Let me find some 1080pcontent and test. OK an iphone 1080p recording plays fine.
So DVB tech person is correct in his analyses.
My iphone 5s records in 1080p
iphone recoding 2180p works fine too.

So H.264 interlaced content cannot be handled by AMD drivers correctly when turning on DXVA.

We've reproduced what we think is the same issue DXVA and H264 corruption

response from AMD

We've reproduced what we think is the same issue as you guys are reporting. I'm using Ace Stream and H264 based content is exhibiting the same type of block corruption you guys see.

We are investigating the issue and will report back as soon as I have more information for you guys.

Thanks for being patient and also for trying to narrow this down on your end. Much appreciated!

UHD and bitrates ?

If it was the bitrate surely UHD which uses higher bitrates works fine.
Just tested with iphone created videos, they all play fine with DXVA enabled for HD.
Here is one example.
DXVA RX480 1691hotfix for AMD Staff v2 - YouTube

if you check this video out UHD working fine with 24mbit/sec bitrate.
RADEON RX480 demo using DVBviewer 4k video - YouTube
this worked from day one.

DXVA RX480 1691hotfix for AMD Staff

DXVA RX480 1691hotfix for AMD Staff v2
some more testing as requested by leafsstean

Hi. I have just tested playing a video that was not captured with DVBviwer and that played fine.
Play the video to get all the details.

DXVA issue being looked at by AMD

Message from AMD

Hey, just letting you know AMD is in the process of looking at your reported issue. We are in the process of trying to reproduce the issue locally. It isn't as black and white an issue as it seems. We extensively test H264/H265 decoding during validation so please be assured we didn't ignore a problem from the get go. Anyway! Hopefully I can reproduce this issue, if not I'll try to follow up with you here.


As AMD are looking into just be patient I suggest.
By the way H264 decoding is really not a big deal. Any midrange CPU can cope with that , in fact my Phenom 1100T CPU which is about 7 years old copes with decoding that using about 5% of CPU....H265 works it is not a big deal.

By the way the answer to the DVBviewer query is yes the recorded video playback also corrupts the image when DXVA is turned on for h264.

After installing the 16.9.1 driver the Crimson GUI does not load.

After installing the 16.9.1 driver the Crimson GUI does not load.
This is causing me grief as I cannot adjust any settings, in particular the fan and the GPU is getting quite warm for no reason. As you can see the GPU is getting close to 80C and I am not doing anything intensive on my PC, the fan should be running much faster to cool it down.

Check out the video

After 16.9.1 installation.

This was supposedly fixed in 16.8.1
[82485] "Failed to create OpenGL context" error message may appear after installation

is happening with 16.9.1
Crimson GUI does not load.
This is important as users cannot modify any settings in Wattman, well I can't anyway

More woe....a report that UHD playback is now not working with 16.9.1 driver.

well it seems for me on the latest drive i cant play any 4k stuff at all now, hardware decoding is totally dead on this card now, no idea why nobody with the 460's is picking up on this, the 460 is the supposed to the next gen HTPC card, perhaps everyone sacked these off and went for the GTX 960 or the 1060

 Another user commented

I can only test some online sample 4k UHD viedos.
It seems still working on my RX460 with LAV and 16.9.1.

But if I use madvr+dxva, it will not work. No videos , only a black window. This is the same as 16.8.3 though.

DXVA - AMD accept that they have a problem.

At last a response from AMD.

We're looking into your DXVA issue. If we need more information, I'll get back to you.
