So it only started at some point after RC1, but before 2.10? (days?
weeks?)  I'm trying of think of things that changed during that time
that might have caused this.  Did you change something on your end?

This may be a affect of the transition from gegl 0.3 to 0.4?

Not likely, especially if it already happened before 2.10.  The 0.4
switch happened right before the release.

In the past, it was related to complicated images with high
resolution and usually setting GEGL_CACHE_SIZE to 2048 or
thereabouts fixed it. Now, it does not.

This sounds like you might have ran out of cache and swap space, in
which case you'd start getting write errors.  These are read errors,
which are much more surprising.

I did the following. I set the following environment variables:

It didn't make any difference.

Ok, so it's not the separate paint thread.  That's a good thing :)
What's the rest of your GEGL setup like?  Are you using any other
environment variables?  What's the thread count?

Matter of fact, GEGL_SWAP was unused.
So, I removed it and reran GIMP. No change.

Do you mean that GEGL wasn't using the swap?  Can you use the dashboard
to see if anything "interesting" is going on while this happens?  Is
the cache full?  Is the swap nearly full?  Do the reported cache/swap
size limits make sense?
