I just noticed a side-effect which may help in debugging this issue... The mouse cursor does not revert to a pointer after doing a right-click.
NORMAL EXPECTED BEHAVIOR (a) Typically, if you are hovering over an editable text area, the mouse pointer is a vertical bar (cursor). when you move outside the text area, such as the window title-bar, the mouse pointer reverts to an arrow. (b) Also, when you right click in a text area, the mouse pointer changes to an arrow, so you can pick something in the pop-up context menu that appears. UNWANTED SIDE-EFFECT BEHAVIOR In this case, right-clicking does not change the cursor to an arrow; it stays as a vertical bar. After this, if you move the pointer outside the text area to the window title bar, the mouse pointer is still a cursor (vertical bar shape). Normal behavior should be as described in (a) above. This also happens for window resize pointers. The mouse pointer stays as a cursor every where in the window after right-clicking in the text area. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1731581 Title: Context menus do not appear for Gtk text areas upon right-click Status in gnome-shell package in Ubuntu: New Bug description: When right-clicking on Gtk text areas (such as an editable text area or a text entry field), a context menu does not appear. The pop-up context menu typically lists options such as copy, paste, etc. EXAMPLES Examples of applications that are impacted include: 1. Gedit Text Area 2. Nautlus (editable address bar) 3. Google Chrome URL bar 4. GtkHash (text entry fields) Interestingly the text areas of some other applications do show pop-up context menu when right-clicked: 1. Libre Office Writer 2. Web pages in Google Chrome that require text entry (such as this web page) RECREATING ISSUE I do not have a consistent way to recreate this issue (yet). When I first log in, the right-click context menus work fine. After some time of usage, the right-click context menus no longer appear. If I use the computer long enough (over an hour) without rebooting, this issue always appears. This issue seems to only affect widgets that require text entry. However, there is one exception I have noticed: the tabs in Google Chrome stop showing pop-up context menus at the same time as this issues manifests itself for the rest of gnome-shell applications with text areas. OTHER CONTEXT MENUS Context menus for other widgets do appear upon right-click, as expected, and work fine. For example, the context menu for window title bars appear when right-clicking on them. The context menu for folders and files in Nautilus also appear when right-clicking on them.
