Bug ID: 100262
Summary: libswrAVX2.so Causes hang with QOpenGLWidget
Product: Mesa
Version: 13.0
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/swr
Assignee: mesa-dev@lists.freedesktop.org
Reporter: ch...@circlecvi.com

Minimal Qt Project sample widget showing issue
Following is some Qt example code straight from their repository that runs
properly using Gallium llvmpipe driver, and Gallium swr driver on AVX enabled
machines (libswrAVX.so).
Running the same demo on AVX2 enabled machines (libswrAVX2.so) causes the
machine to hang at 100% CPU usage and never recovers. The library detects AVX2,
however GL calls in the paintEvent appear to be hanging the machine (IE no GL
calls, no issue)
Please see attached for the QOpenGlWidget example (Qt v5)
