Loadtest issues about gocast HOT 16 CLOSED

Cut off chat will be fixed sometime before the semester starts.

from gocast.

@ all Thank's a lot, you've been incredibly helpful!

from gocast.

Sometimes number of viewers isn't displayed
Edit: Also scrolling in chat seems to be broken sometimes, even scrolling down manually won't work
Edit 2: Resizing the window moves the chat up
Edit 3: Sending empty messages is possible fixed
Edit 4: I'm using Firefox 87.0 on a Windows 10 machine

from gocast.

comments / chat on the stream needed a while to show up after they're entered (~14 secs).

Edit: This seems to be not the issue but rather the chat page is extended beyond viewable area at the bottom, meaning new messages are not seen unless a newer message pushes them upwards. (Firefox on Windows 10)

Edit: Also scrolling seems to be broken sometimes, even scrolling down manually won't work

Exactly, I cannot scroll further at this point.
Element inspector reveals there's one more line to that last message.

The problem repeatedly solves itself when new messages appear and reappears later.

Edit: It seems like the problem appears if a message is received while your chat is not completely scrolled to the bottom.
Edit 2: No, also happens without that :D
Edit 3: So yeah, this is all just because the "Send a message" form overlaps the chat. If the most recent message is only a single line, it is obscured completely, making it seem like everything was fine.

I also experience the cutoff issue. Using Firefox 86.0 (build nr 20210228220141). Refreshing doesn't solve it.

from gocast.

Also rendering all messages might lead to unnecessary high memory consumption ond/or slow scrolling

from gocast.

I'm using Firefox 87.0, Linux.

• Bottom of the chat is cut off (as reported above already).
• Participator count wasn't displayed. Refreshing helped, can't reproduce reliably.
• Some chat messages seem to get lost.
• The course name ("Lasttest") is displayed at the very bottom, are we supposed to be able to scroll? Edit: If you make your window very flat, you can't even see the whole video.
• Stream seems to be stuck at loading. (The loading circle thing keeps being there and the stream doesn't play reliably.)
• The bad at the bottom of the video is sometimes invisible. I still get the tooltip info (like "Mute"), but the symbols are not displayed.

@Raupinger, I'll test on your version of Firefox soon! Which OS do you use?

from gocast.

I have the same issue on Mozilla Firefox 87.0 BuildNr 20210324205532
I'm using Fedora 33 5.11.7-200.fc33.x86_64

from gocast.

I also experience the cutoff issue. Using Firefox 86.0 (build nr 20210228220141). Refreshing doesn't solve it.

Same for Firefox 87.0, Windows 10; Changing max-height: calc(100vh - 5rem); to max-height: calc(100vh - 9rem); in main.css line 1390 (in .chat-class for @media(min-width: 768px)) fixes that, but might not be the optimal solution for other browsers.

Posting this Message with a large amount of unicode modifiers completely hangs up the chat. Don't see any new messages and cant send anything. reloading solves the problem.

@Raupinger, I'll test on your version of Firefox soon! Which OS do you use?

that would be Manjaro Linux.

You requested the error messages from the console - those are mine:

Firefox 64-Bit 87.0
Windows 10 20H2 (Build 19042.867)

Edit 1: Those were the shown messages after a single page refresh and pressing the play button on the video.
