penguin42hey16:54
penguin42finally starting to cool down a bit here16:54
sebsebsebpenguin42: yep here  too16:55
zxmpidown to 23c here today, was over 25c yesterday17:04
penguin42it's claiming to be down to 20c accoding to the weather app on the bar17:07
daftykinsaaaah... a glorious breeze!22:17
daftykinsi might be hopping over to Exeter sometime soon22:17
daftykinsi just found a Brewdog restaurant there, that ought to be fun22:17
penguin42hmm I think there's one here as well22:32
daftykinswe drink a fair bit of their "Lost" in cans down at my dentist pal's practice22:36
daftykinsout of hours, of course xD22:36
daftykinsi think he'll be jealous once i mention having the chance to visit one o' these22:36
daftykinshmm of course visiting England means finding a spare phone and a UK SIM22:37
penguin42so I just spent an hour chasing something truly obscure22:39
penguin42https://cdn.mastodon.org.uk/media_attachments/files/111/042/671/143/131/984/original/468f76ad3191872c.jpeg   you see that green smudge under 'license'22:40
daftykinsyep22:40
penguin42ok, where do you start debugging it22:41
daftykinsprobably dragging in another white window to start, to rule out the monitor22:41
daftykinsthen again scrolling would do that xD22:42
penguin42dragging a white window over it, the white window is fine22:42
penguin42scrolling follows the scroll22:42
daftykinshrmm, separate browsers on the same page next i'd try22:43
penguin42chromium doesn't exhibit it22:43
daftykinsbut the Fox can do no wrong, in my book!22:44
penguin42I will note the green is flickering and jittering22:44
daftykinsooh22:44
daftykinsright click -> inspect element find anything other than background blankness?22:44
penguin42worlds most boring html22:45
daftykinswow, ok... amaze me!22:46
penguin42daftykins: OK, let me tell you another one - screenshot doesn't show it22:46
daftykinsO_O22:46
penguin42daftykins: Disabling hardware acceleration doesn't help22:47
penguin42daftykins: And restarting ff doesn't help22:47
penguin42daftykins: Changing the sharpness on the monitor makes it go away22:48
daftykinsoooh22:48
daftykinsso it was in the display, wowzer22:48
penguin42odd isnt it22:49
daftykinsthat's quite the tricky one!22:49
penguin42but it's only that page it's showing it on22:49
daftykinsi wonder what about that region makes your monitor go so nutty22:50
daftykinshere's one for fun, what about rotating?22:50
daftykinswould the pattern perfectly rotate 90 degrees to fill the same portion?22:50
penguin42my suspicion is it's an aging fault on the monitor; it seems very sensivie to the exact background colour; if I edit the background colour it goes away22:51
daftykins:D22:51
penguin42I think it's triggering on the right hand slope of the 'v' in approved22:51
daftykinsi have quite a number of vertical lines when i cold power-on my 2008 CCFL backed LCDs now, after a warm-up these disappear22:51
penguin42are they black lines?22:52
daftykinsoh yeah that does look like the origin22:52
daftykinsthey're a bit of a mix, some colours - some black so presumably unlit columns22:52
penguin42yeh22:52
penguin42I did have another Dell monitor that had settings related artifacts - but they were much larger scale and much less image specific22:54
daftykinshere's how one looks - https://i.imgur.com/VcZyb35.jpg22:55
penguin42oh yeh, that's normally a connection to the panel going over time I think22:56
daftykinsapparently a bit of hairdryer action between the layers can help, but since it disappears on warmup i have just accepted it22:57
penguin42yep22:57
