The latest NVIDIA Linux driver has reached 340.46 with a few bug fixes. Here’s how to easily install it in Ubuntu 14.10 or Ubuntu 14.04 via PPA repository.
What’s new in NVIDIA 340.46:
Fixed an OpenGL issue that could cause glReadPixels() operations to be improperly clipped when resizing composited application windows, potentially leading to momentary X freezes.
Fixed a bug that could prevent the GLSL compiler from correctly evaluating some expressions when compiling shaders.
Fixed a bug that could cause nvidia-installer to crash while attempting to run nvidia-xconfig on systems where that utility is missing.
Added option UseSysmemPixmapAccel to control the use of GPU acceleration for X drawing operations on pixmaps allocated in system memory.
Release note and supported GPUs are available in the Nvidia page.
