Video corruption

[pwhodges 2079]

From time to time I get video corruption in the Windows client.  This has persisted through many betas and the current stable.  It appears as a regular grid of lines, whose spacing varies, and which may be horizontal, vertical, or both.  The pattern varies or comes and goes if I change the size of the window.  I've not reported it before, because it is hard to capture - it may be a week or two between occurrences, and when I start a screen capture it may disappear when I try to show the effect.  The attached video shows it, with changes when I adjust the window size near the end.

I suppose it's most likely to be hardware (Intel A380) or the driver (it's persisted through many driver updates).  I have two A380s, and I'm pretty sure it's shown on them both.  The source video is AV1.

I cannot get the problem to appear using the web client on the same machine.

Has anyone else had this happen?

PW,

Check the output size of the transcode.  Are the dimensions divisible by 8?  It seems strange, but sometimes this can effect the transcode quality.
