I have found a way to trigger issue quite reliably. Operating System: Debian GNU/Linux KDE Plasma Version: 5.25.3 KDE Frameworks Version: 5.94.0 Qt Version: 5.15.4 Kernel Version: 5.18.12-1-siduction-amd64 (64-bit) Graphics Platform: X11 Processors: 4 =C3=97 Intel=C2=AE Core=E2=84=A2 i7-6600U CPU @ 2.60GHz Memory: 7.7 GiB of RAM Graphics Processor: Mesa Intel=C2=AE HD Graphics 520 Manufacturer: Dell Inc. Product Name: Latitude E7470 I am using an external DELL monitor running @2560x1600 pixel @60Hz via DisplayPort connection. Notebook lid is closed. =3D=3D> This system works really stable with no issues for most of time, ap= art from the black screen that is described here. While at first it seemed the issue occurs randomly and more or less seldom,= I finally have found a website that almost always triggers this issue. It occ= urs that often now, that it even is not logged in dmesg all times. Unfortumately, to reproduce the issue, you need to have an account at websi= te http://www.spinchat.de (there is an English version as well, if that should matter to you). How to replicate issue: (1) Log into spinchat. (2) Use spinchat as one would normally do, i.e. create an account if you do= not have one, create user name, log into standard server, enter any chat room, = open dialogue window with any chat buddy. (3) Spinchat rooms have a kind of menu bar with soft buttons at bottom of screen labelled "Hauptseite" ("Main Site", always visible), and a number of room names and chat person buddy names. They are simply small rectangular b= oxes with another room name, main site access, chat buddy nick name. You can hov= er mouse arrow over them and mouse icon will become a hand etc. (4) BUG, happens with this website always when I use it, sometimes it won't show, sometimes it shows several times consecutively. =3D=3D> While in a chat room, hover mouse cursor over menu icon "Hauptseite= " or another room name menu icon button, or another chat person menu icon button. The mouse button changes to a hand and after that screen becomes dark. issue triggered. =3D=3D> This does not always happen. =3D=3D> This happens in many many cases, it happens way too often to say it= is unrelated to black screen issue. =3D=3D> Sometimes black screen is seen for several seconds until it wakes u= p, sometimes it is very briefly. =3D=3D> Sometimes dmesg gets an extra log entry, mostly it does not after i= t has been logged once or a few times. =3D=3D> Issue is triggered while only hovering mouse over soft menu key but= tons and also when actively pressing mouse button over such a soft menu key button. This really is an annoying error and it has been around for such a long tim= e I wonder why it could not yet be fixed. --=20 You may reply to this email to add a comment.
