Bug ID: 102315
Summary: GPU Hang when replaying API trace of lightsmark
Product: Mesa
Version: 17.2
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
Assignee: mesa-dev at lists.freedesktop.org
Reporter: jason at jlekstrand.net
QA Contact: mesa-dev at lists.freedesktop.org
While trying to debug a perf issue in lightsmark, I took an apitrace and, when
replaying it saw GPU hangs on release builds and assertion failures on debug
builds. The assertion failure was because we tried rendering to render to
something that that clearly isn't renderable (it was DXT3) and it looks like it
was hidden because it was inside of a display list. Trace can be found here:
