Odd resizing behavior on git HEAD

Odd resizing behavior on git HEAD

For the past week or so, I've noticed a change of behavior for emacs
frames: when I create a new frame, it appears at the default size and
location, as normal. If I then move and resize it using the window systems
"snap to side" functionality (that is, I drag the window from the titlebar
to the edge of the display, the window manager shows me a preview of the
window full-height and half-screen width, placed on that edge), and then
release it. Until sometime a week or two ago, the frame was correctly moved
and resized; today (and for a fews days, at least), its upper-right corner
is placed in the same position as before, but the size is unchanged. If I
repeat the operation a second time, the window is placed in the same
position, but this time it *is* resized.

It's possible that this change is due to an os/window system change, but
that would require some very coincidental timing.

Has anyone else noticed a change similar to this? My current window system
is unusual (x display via xwayland under chromeos), but the previous
behavior has been stable for at least a couple years.

Thanks,
~Chad

What X toolkit are you using?

If this is as easy to reproduce as you sketched above, then my first
suggestion is to bisect master until you find a corresponding change.

I was able to trace it down to that os/window system change, so it's not an
emacs effect after all.

Thanks for the advice, and sorry for the noise.
