Public bug reported:
changelog:
· Added code to forcibly terminate long-running CUDA kernels when Ctrl-C is
pressed.
· Fixed a bug that could cause occasional memory corruption problems or
segmentation faults when running OpenGL applications on Quadro GPUs.
· Fixed a deadlock in the OpenGL library that could be triggered in certain
rare circumstances on Quadro GPUs.
· Fixed an interaction problem between PowerMizer and CUDA applications that
caused the performance level to be reduced while the CUDA kernel is running.
· Made CUDA compute-exclusive mode persistent across GPU resets.
· Fixed the order of outputs in the GPUScaling nvidia-settings property.
· Fixed a bug that caused graphics corruption in some OpenGL applications when
the Unified Back Buffer is enabled the application window is moved.
· Fixed a bug that caused glXGetVideoSyncSGI, glXWaitVideoSyncSGI, and
glXGetRefreshRateSGI to operate on the wrong screen when there are multiple X
screens.
· Fixed a bug that causes corruption or GPU errors when an application paints a
redirected window whose background is set to ParentRelative on X.Org servers
older than 1.5. This was typically triggered by running Kopete while using
Compiz or Beryl.
· Fixed a bug in VDPAU that could cause visible corruption when decoding H.264
clips with alternating frame/field coded reference pictures, and a video
surface is concurrently removed from the DPB, and re-used as the decode target,
in a single decode operation. This affected all GPUs supported by VDPAU.
· Fixed a bug in VDPAU that could cause visible corruption near the bottom edge
of the picture when decoding VC-1 advanced profile clips whose heights are not
exact multiples of 16 pixels, on G98 and MCP7x (IGP) GPUs.
· Enhanced VDPAU to better handle corrupt/invalid H.264 bitstreams on G84, G86,
G92, G94, G96, or GT200 GPUs. This should prevent most cases of "display
preemption" that are caused by bitstream errors.
· Fixed an X server crash when using the VDPAU overlay-based presentation queue
and VT-switching away from the X server.
· Enhanced VDPAU's detection of the GPU's video decode capabilities.
· Fixed a bug in VDPAU that could cause ghosting/flashing issues when decoding
H.264 clips, in certain full DPB scenarios, on G98 and MCP7x.
· Fixed VDPAU to detect an attempt to destroy the VdpDevice object when other
device-owned objects still exist. VDPAU now triggers "display preemption", and
returns an error, when this occurs.
· Enhanced VDPAU's error handling and resource management in presentation queue
creation and operation. This change correctly propagates all errors back to the
client application, and avoids some resource leaks.
