[13:21] https://p.mort.coffee/GeX.png sometimes, the screen kind of flashes and firefox resizes to be behind the dock like this [13:22] mort: hmm, we had an early 20.04 similar like that, let me look that up [13:24] mort: check if its bug #1849787 [13:24] bug 1849787 in Dash to dock "The dock is shown in front of full screen windows since 19.10" [Unknown,New] https://launchpad.net/bugs/1849787 [13:27] and bug #1852254 [13:27] bug 1849787 in Dash to dock "duplicate for #1852254 The dock is shown in front of full screen windows since 19.10" [Unknown,New] https://launchpad.net/bugs/1849787 [13:28] in my case, xscreensaver didnt fullscreen, and made the dock still visible [13:36] https://p.mort.coffee/D0p is journalctl's output when it happens [13:37] none of those bug reports look super relevant though it's not a fullscreen window, just a maximized one [13:37] so the dock and the top bar should be there, the window just shouldn't go behind the dock [13:37] mort: are you on intel graphics? [13:37] yes [13:37] wich one [13:38] Mesa Intel(R) HD Graphics 630 (KBL GT2) [13:38] right, so that would match the bug for sure [13:38] mort: try it with xscreensaver perhaps? see what it does? [13:39] showing the previews with xscreensaver works how I would expect at least, it covers the entire screen [13:39] I'm on wayland though, so it's in xwayland [13:39] oh [13:40] did you try it on xorg to reproduce? [13:40] there is nothing to try, it just happens every now and then during normal usage [13:40] but I could try to just use X for a while and see if it ever happens [13:41] there's always something you can try to reproduce [13:44] well, gnome just crashed and I was booted back to gdm [13:44] lol [13:46] alright, I'll relog into X11 and just try to use firefox for a while I suppose [14:05] well, it hasn't happened thus far in x11 [14:05] seems to only be a wayland thing [14:05] ok mort
