Video corruption

[pwhodges 2067]

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?
