Mavericks resizes application windows and moves them around

this resizing and repositioning is still happening two years after the initial post!

Still going and going strong for me. Two external 4K displays with my up to date mid 2014 macbook pro, and every time I wake it up from sleep nearly every single window is moved, sometimes across displays, sometimes resized, sometimes off both screens entirely requiring me to fiddle with the menus to get it full screen so I can resize and move it. EVERY TIME.

This is beyond an inconvenience, it's a nuisance and makes using the machine incredibly aggravating. I must lock my machine for security, which means I must move windows around every time I need to use it.

It's 2015, this has been occurring for years now. I think it's time to put some effort into fixing it.

Still going strong for me as well, I'm still running Yosemite, however. Can anyone confirm if this is fixed in El Capitan? Force quitting Dock does fix the problem, but I have to do it every time I unplug my 2 external monitors from my MBP (late 2013 model). I had less problems with beta the Windows 10 preview builds on my Surface Pro 3, seriously...

One of the easy ways I can tell if the window position is screwed up is if I hover over a link in Chrome and the web address doesn't show at the bottom of the browser window, but instead at some random point on the screen. That position becomes the bottom-left of the window if I attempt to resize it. So if you see that happen, force quit Dock, then you won't lose your window position if you try to resize.

Just happened to me when running El Capitan (10.11.1), so obviously not fixed!

Same here. Happened to me just now, for the first time - 10.11.6 (15G31) mbp retina 13" half 2014

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.
