Created attachment 148210 [details] showing the black square (bottom right) where a notification should be SUMMARY Steam will produce popups on the lower right hand corner of your main screen. While it doesn't respect where the panel is (like on Windows), that's an issue for another time (or for Valve). Sometimes, it will pop up a notification and the notification will be all black (like a compositing issue perhaps?). I'm not the only one who has seen it, I have attached a screenshot from a thread from Reddit. STEPS TO REPRODUCE 1. Install Steam 2. Get a notification (common ones are: install finished, friend came online, new message, etc) 3. Under certain scenarios the popup message will be entirely blacked out and you are not able to read the contents. OBSERVED RESULT Black rectangle instead of message contents EXPECTED RESULT Message contents shown SOFTWARE/OS VERSIONS Linux/KDE Plasma: Wayland, Kernel 5.17.2-1-default (available in About System) KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Seems to be fine under X11 and I am not able to produce it 100% of the time, may depend on certain settings. This is the reddit thread: https://www.reddit.com/r/linux_gaming/comments/tpwlqk/steam_notifications_appearing_as_black_boxes/ Attached is a screenshot from that thread. I tried getting a friend to send a message, and it appeared correctly, but it wasn't working previously.
Ideally Steam would be using system native notifications, but we should fix this, yeah.
I was unable to get one of such notifications. Do you know if there's a way to get one so we can reproduce and fix?
I could reproduce, still it would be good to know how to get it easily to be able to investigate properly.
I did some testing and got a Steam friend to send me message while the chat was in the background. The popup appeared fine. Then, shortly after, I got a notification that a friend had either come online or started playing a game. That one came in as blacked out. I should note that in the Reddit thread someone reported seeing the same issue in sway, so it might be an issue with xwayland?
This issue has been fixed by the recent major Steam update, I believe.
