#7831 new bug

Brainwash screen saver will crash haiku

Reported by: pulkomandy Owned by: korli

I tried to install this screensaver in Haiku, but it crashed the system to the point I can't even enter KDL. The source is available, so I tried to recompile it. The outcome was a bit differer, with a drop to gdb. Closing gdb made Haiku crash anyway.

Investigation of the crash in GDB (the one I get after recompiling) shows a race condition in the way the window is created and connected.

I noticed use of BWindowScreen tends to crahs the intel_extreme driver, so it's safer to test this using VESA (or fix the intel_extreme driver to handle 8-bit video modes again).

Well, this is still crashing in various ways... I tried on another machine today.

  • With the intel_extreme driver: screen shows garbled data (which is probably ok, the Haswell driver is incomplete and doesn't handle video mode changes properly). No way to exit the screensaver by moving the mouse, but at least I can switch to another workspace and kill screen_blanker
  • With VESA: the screensaver crashes, then app_server crashes. Attaching serial log and app-server save-report.

Still here in hrev52561; it happens on exit of the screensaver.

I got app_server crash in ServerWindow::MakeWindow when running AccelerantConsumer. Maybe related to B_CURSOR_ID_NO_CURSOR.
