Application: kwin_x11 (5.14.1)

Qt Version: 5.11.1
Frameworks Version: 5.51.0
Operating System: Linux 4.16.3-041603-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
- What I was doing when the application crashed: Waking laptop up from resume. Plasma desktop icons also have corrupted text due to this bug. Only way to fix is to restart both Kwin and Plasma Desktop. I have Nvidia 396 proprietary drivers installed.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
