presentation corruption with 27.20.100.8280

Hi,

I'm the developer behind the SEGA Dreamcast emulator https://redream.io.

With the latest Windows driver build (27.20.100.8280) we've had multiple reports of the output being corrupt for numerous users. Two confirmed GPUs were the HD 405 and HD 530.

The corruption seems to only exist for some users when windowed, going away when fullscreen. A photo of what the corrupt output looks like:

And a video of what the corrupt output looks like:

Note in the above video a user was attempting to capture an apitrace for this report, but the corruption doesn't show up when replaying the trace, only when recording. The recorded trace is attached in case its useful regardless.

Hi,

Is it possible to get some feedback regarding this (e.g. is it being tracked internally)?

Better yet, if it's possible to workaround the issue right now I'd love to know how. At this point I have a steady, daily stream of users being impacted by this that I'd love to get back working.
