** Description changed: - -- BACKGROUND info -- (ie. skip!) I upgraded to 18.04 last night from 17.10 (Ubuntu with GNOME, but also XFCE & MATE DEsktops were installed). I logged in last night & noticed nothing unusual (slow login, crash & apport bug report made [duplicate]). Otherwise upgrade was perfect. Last night I only used MATE. -- END background - Today I logged into GNOME (first login since upgrade), my screen config - was changed (as if side-by-side) so I altered to match my config - and - now on top (secondary) screen left side of screen I get this few pixel - wide graphic 'bar' type glitch. + Today I logged into GNOME (first login since upgrade), my screen + positional config was changed (as if side-by-side) so I altered to match + my config - and now on top (secondary) screen left side of screen I get + this few pixel wide graphic 'bar' type glitch. - It alters with screen-draws; having minimal movement is nothing on - screen is drawing. If you move mouse it jumps more, if you move windows - the movement is even more - when I start music (audacious) which has a - graphic audio metre (dancing with music) I get lots of activity on the - glitch-bar. + It appears to dance when something moves on the screen (eg. cursor + movement, or audio-metre bars on mp3 player (audacious). Moving the + cursor alone causes minimal 'dance' in the glitch, moving a window + around causes a lot higher-faster dance in the glitch. When I start + music (audacious) with the audio metre (dancing with music) I get lots + of activity on the glitch-bar; if music is stopped (audio-metre is + static) glitch becomes minimal. - If I move audacious below (top) screen it still acts as if on screen (my - screen placement i think is reason for this), but if I minimize the - window the glitch has minimal movement, likewise if I move audacious to - lower (primary) screen and move the bar off display. + If I move audacious below screen (or out of display) screen it still + acts as if on screen (my screen placement i think is reason for this; + top right 1/3 of screen is to right of below screen; left 1/3 of bottom + screen is to left top screen), but if I minimize the window the glitch + has minimal movement, likewise if I move audacious to lower (primary) + screen and move the bar off display. As stated, the vertical-graphic-lines-glitch appears to be related to movement or redrawing of stuff on screen. If I stop music and have ~everything static but type into the `hexchat` screen on the bottom, the vertical-graphic-lines-glitch jumps on each keypress (or its being written to screen). If i hit random keys quickly the jumping movement is faster than slow keypresses If I make no movements, glitch still has movement; maybe 2-4 moves per second., but a fraction of the 'jumps' (or movement) of when there is graphic movement. OF NOTE: As I type this into chromium, the 'glitch' is the smallest its been and NOT moving to each keystroke which is different behavior to - terms, hexchat etc. + terms, hexchat etc. When I first login, its not evident, it takes a few + minutes to become visible. - This behavior is only evident in GNOME. + This behavior is only evident in GNOME (on X) guiverc@d960-ubu2:~$ lsb_release -a No LSB modules are available.
