the texture is corrupted, and it will contain a small rectangle with
pseudorandom pixels.
And the graphics being drawn when the SGX HW reset happened can be
corrupted (as the operation was interrupted and state before the reset
isn't recoverable).
This is a bit different: in these cases I rarely see any lines from SGX in the
syslog. From there, everything appears fine, but the textures are corrupted.
Note that on most(?) devices it doesn't seem to happen at all, at least
with the pre-installed software.
But e.g. the 3rd party Maep application seems to make triggering of this
issue (at least on some devices) easier, especially as/when it's doing
window updates even when it's not visible (which is a clear use-time
and resource usage bug in Maep).
In my case, I'm sure I've seen it when I was actively using the device. But now
that I think of it, in all cases when I saw it I had a dialog on top of the
clutter stage: the "download route" dialog, which also causes some network
traffic to retrieve the route and then some CPU activity to parse it into a path
and draw it on the stage, via the cairo functions.
It is quite possible that drawing happened while the clutter stage was covered
by a dialog.
