Hello Christopher, In some recent tests: a. It occurs with monitor connected either on the laptop's HDMI, or the docking stations HDMI. b. In one case monitor is VGA (with converter), in the other it is HDMI. c. I have no access to other type, for the moment. d. I have not disabled the card, but I have used it only with power supply, so perfromance profile should be enabled. e. The nvidia proprietary does not work correctly. It causes a lot of issues, including image corruption and freezing of all when suspending. Also, it does not properly drive the externral monitor. f. I will try to check with the image you mentioned. However, the problem seems to exist since quite some time. My system is fully updated to the most current modification. g. The flickering on basic monitor changes with what windows are open. For example, it is always worse when evolution is maximized there. Some times it goes away if I open a gedit write some few lines and then mark them using the mouse. Sometimes it just needs few clicks within the flickering area or even just leaving the cursor there for few seconds. h. For the external monitor issue, the two programs that suffer most are HipChat and Viber. Both are fine if one part resides on the standard monitor.
