I'm a linux newb so I'm sorry I can't be more detailed, but I can verify that my bug report is accurate. Dell XPS 13, 9350 Debian Testing branch My uptime was around 2 weeks, and I usually do a dist-upgrade every other day or so. Yesterday I had to reboot my system, and that's when all went haywire. It's hard to which one, but I'm quite sure that a recent update caused all this. KWin crashes and I lose all my desktop applications and processes when coming out of sleep mode 80% of the time. It seems to be closer to 90% when I sleep it by closing the lid versus using the sleep option in the kmenu. I'm getting random lags when moving windows around, and sometimes the decorations will crash when maximizing a window -- happened with Chrome and Okular this morning. 4 or 5 times in the past day when I close the system settings (doesn't matter what section I'm in, Display settings, logon and logoff, etc) KWin crashes. I feel like this is a pretty significant issue considering how incredibly stable everything has been the past year, I usually wouldn't report bugs unless they are fairly detrimental.
If it crashes, please provide a backtrace. A small icon with a "sad face" should show up in the systray. There you can generate the backtrace in the developer information tab. Without the backtrace we cannot investigate the crash.
Right after posting this, I had Kwin crash again after waking, and then (I was in fact mistake) ksmserver crashed (not Kwin) when snapping a window to the side of my screen. I didn't grab the error reports, but I did go through both of them and the red highlighted section on both said something about libc.so.6 causing the error. Next time it happens, I'll save the crash reports and post them here Thank you
Here's the backtrace for the ksmserver crash on resume from standby: Application: ksmserver (ksmserver), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Did you add/remove input devices during the suspend? Qt does not seem to like this.
The only thing I may have connected/disconnected while sleeping, is the power cord (laptop charger). Here's the backtrace for the crash when snapping a window to the top of the screen to full size it.

Thanks for the update. This crash is in Qt code; reported for Qt 5.5, but also recently for Qt 5.7.1 on debian testing. *** This bug has been marked as a duplicate of bug 373865 ***
