Mavericks resizes application windows and moves them around

Yup, same here.

Have reported it to Apple and they have sent it to their engineers with a copy of a system dump they asked me to make.

Incedentaly, I created an external partition with a new instal of Mav on it and it still heppened.

Also... It happened when booting from a Mac USB instal image....

I have a copy of MLion on another external HDD and that's fine.

I am having the same issue as well. Every time my mac falls asleep, windows are moved partially off the screen when my computer wakes.

The most annoying part is that the window will snap back to the partially-of-the-screen position when I attempt to move it back.

I change refresh rate to cure each time.... right pain though.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Great Idea.

Done.

I suggest everyone else haveing this issue does the same.

Thanks Eric.

Not bad at all CamberleyDaz!

I used the link that Eric has put in his post.

Lets hope this gets sorted asap.

Same issue here. iMac 27" 2011. Colleague of mine also is affected, Macbook Pro 2012. We are both using external displays as well as the native display, if that is of any significance.

EDIT: found another thread describing the same issue here - also providing a possible solution: https://discussions.apple.com/thread/5515610?answerId=23632225022#23632225022

PS: i tried booting in safe mode (see link above). for me it didnt help, actually now its worse, since I just had multiple windows/applications affected by the resizing snapping. as of before, only 1 window went crazy.

Apple now have this reported as a bug!

Success, now for a patch....

I have a MBA and an iMac both doing it now. It's a bug and needs to be fixed.

On another topic, at least Mavericks fixed the bug where Safari would forget the previous window state.

Had the same problem. Fixed it as follows:-

Use Alt 'on' to enter restore mode.

Use disk utilitities to repair permissions

Use terminal to 'resetpassword'

Use reset password dialogue box to reset permissions (at bottom).

Works as used to now.

Hi Geewizzpip.

Thanks for the suggestion - for me this did not work though.

The fact that this symptom occurred whilst I was booted from a Mavericks installation USB thumb-drive, and not the internal fusion, tells me that it can only be something fundamental inside the Mavericks display drivers. Thay have definitely changed as there are 1/2 as many resolutions available.

Now to chase down that Apple repair case...

This happens on my MBP every time the display sleeps. I wake it up to find my windows resized and often jammed into positions where I can not grab the drag bar to reposition them.

Same here with a MacBook Air 13 and a iMac 27.

The problem occurs with any App (even Finder!) since i have updated to Mavericks.
