Lately I have been seeing this odd block highlighting issue in the master build. Unfortunately I do not know how to recreate the issue, and the rough estimate from when this started happening is also bad (some time last month).
The best way to explain this issue is this gif:
For some reason, the region between lines 24 and 42 gets highlighted (not selected) when the mouse cursor hovers on any text in that region. These two points are not fixed; this could happen at random in different files.
I cannot make this go away by reverting the buffer or disabling *all* the minor modes or changing the major mode to fundamental mode.
The only ways this gets 'fixed' is if I kill the buffer and re-open the file, or if the file is modified outside of emacs and I revert the buffer.
But then this issue can repeat at any time in future.
Questions:
- Does this behavior look familiar to any recent commit to anyone?
- Where can I start looking so that I can provide a useful bug report? As even disabling all minor modes and changing to fundamental mode retains this issue, I do not what else to look at.
