Comment 15 for bug 1854621

Ubuntu impish desktop live QA-test of
- dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)

at the try/install query (maybe-ubiquity) I get video glitches at top of wallpaper

changing wallpaper gets black background or glitchy-wallpaper (varying each time) - ignoring that for now

VIDEO GLITCHES on wallpaper are actually appearing on the workspaces display (may not be gnome terminology sorry); which I did not expect (has it done that before? I've forgotten?).. in fact they're on the screenshots?? Looking at bug report they've occurred before; maybe it's just me not testing gnome very often (or not on this old slow box)
