Priority: medium Bug ID: 69805 Assignee: dri-devel@lists.freedesktop.org Summary: flightgear crashes on r600 (rs880) Severity: normal Classification: Unclassified OS: Linux (All) Reporter: marvin24@gmx.de Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
flightgear 2.12 crashes on git mesa. Works with R600_LLVM=0. I initially thought it is due to missing trig functions, but after applying a workaround (from some other bug), it still crashes, so this must be something different.
