[kwin] [Bug 433905] kwin crashes inKWin::DrmGpu::~DrmGpu() with chrome (wayland support) when creating new window
https://bugs.kde.org/show_bug.cgi?id=433905 --- Comment #3 from Vlad Zahorodnii --- @Alois can you please install debug symbols for kwin? but yeah, it's odd that kwin quits when a new chrome window is opened. fwiw, I can't reproduce this bug. I have an amd video card. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=433905 --- Comment #2 from Alois Wohlschlager --- Perhaps more interesting is why kwin exits in the first place. Can you please execute "break exit" in gdb and check whether you get the same backtrace as me? Ideally with more debug symbols than I have (sorry for that).
