-- Information about the crash:
Report:

Package: kwin-wayland
Version: 
Severity: normal

Dear Maintainer,

On my Debian testing (forky) system, kwin_wayland consistently crashes with a SIGABRT when I exit or restart KWin.

This does not occur during normal use, only at shutdown/restart of the compositor. The session otherwise runs fine.

Steps to reproduce

1.Start a Wayland session with kwin_wayland.

2.Restart or Logout then Log back In

3.Observe crash.

Observed behavior

-kwin_wayland aborts with signal SIGABRT.

-Backtrace shows failure inside libepoxy when trying to call glDeleteRenderbuffers after the GL context has already been destroyed.

Relevant backtrace excerpt:

#8  epoxy_get_proc_address ("glDeleteRenderbuffers")
#10 epoxy_glDeleteRenderbuffers_global_rewrite_ptr
#11 KWin::GLFramebuffer::~GLFramebuffer
...
#29 KWin::QPA::EGLPlatformContext::makeCurrent
#33 QQuickWindow::~QQuickWindow
#38 KWin::CompositedOutlineVisual::~CompositedOutlineVisual
#43 KWin::Outline::compositingChanged
#47 KWin::WaylandCompositor::stop
#49 KWin::Compositor::reinitialize
...
#68 main (main_wayland.cpp:622)

Warnings also appeared in gdb about mismatched build-ids and deleted mmap files, but those are likely unrelated (normal for testing).

Expected behavior:

KWin should shut down gracefully without aborting, even if GL resources are cleaned up after the context has been destroyed.

The crash can be reproduced every time.
