Yes, see it consistently in large files that you have edited for a long time. Typically happens after you attempt to copy/paste large chunks of it.

There is an easy but non permanent fix that I have deduced after dealing with this for a long time.

1. make all layers visible
2. Ctrl-A (select all)
3. Copy, select an origin, any origin
4. Make a new file
5. Paste.

And Viola! you can select/trim/extend/etc again.  I have no idea what causes this but it has to be some zoom selection stuff up or something.
