The workaround that I found was to disable flipping in nvidia-settings but this shouldn't be a permanent fix because it potentially degrades OpenGL performance:
Option "NoFlip" "boolean" Disable OpenGL flipping; see Chapter 17 for a description. Default: OpenGL will swap by flipping when possible. [...] o Flipping: When OpenGL flipping is enabled, OpenGL can perform buffer swaps by changing which buffer the DAC scans out rather than copying the back buffer contents to the front buffer; this is generally a much higher performance mechanism and allows tearless swapping during the vertical retrace (when __GL_SYNC_TO_VBLANK is set). The conditions under which OpenGL can flip are slightly complicated, but in general: on GeForce or newer hardware, OpenGL can flip when a single full screen unobscured OpenGL application is running, and __GL_SYNC_TO_VBLANK is enabled. Additionally, OpenGL can flip on Quadro hardware even when an OpenGL window is partially obscured or not full screen or __GL_SYNC_TO_VBLANK is not enabled. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283979 Title: moving windows causes the top bar and the launcher bar to flicker To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1283979/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
