Description guimarcalsilva 2022-07-18 21:52:46 UTC
SUMMARY

Sometimes dragging image from Web browser to the panel makes the screen go black. This can take a few seconds to happen. Keep moving the dragged image all over the panel to trigger the bug. Also try ALT+Tab to switch between applications and drag the image over them as well.

STEPS TO REPRODUCE
1. Open image in a browser (tested with Vivaldi, Chrome and Firefox)
2. Drag the opened image to the panel
3. Keep dragging the image all over the panel until the screen goes black, sometimes it helps if you have another application open (eg. Okular) and use ALT+Tab to switch and move the image you're dragging to them. It takes a bit of time to happen, but eventually, the screen will go black.

OBSERVED RESULT

The screen goes black but doesn't seem like it crashes, because Dr. Konqi never gets triggered. When the screen goes black it's still possible to invoke Krunner. Since Dr. Konqi never shows up, the terminal output for plasmashell is all I have:

Comment 1 Nate Graham 2022-07-19 19:23:51 UTC
It sounds like KWin crashed and Plasma failed to re-launch automatically due to Bug 448475. If that's the case, can you get a kwin_wayland backtrace for the crash? You can see the latest ones with `coredumpctl list kwin_wayland`.

Regardless, cannot reproduce on Wayland with current git master.

This is odd but that command says "No coredumps found" no matter how many times I make the session crash. Coredumps are enabled on my system as there are coredumps for Plasmashell (unrelated to this bug), so I don't know why there's none for kwin_wayland.

I'm afraid there's not much info I can give unless there's another way of diagnosing the problem. :(
Comment 3 Nate Graham 2022-07-19 20:17:10 UTC
Ok, then maybe that's not what happened. Did *Plasma* crash and fail to restart? What does `coredumpctl list plasmashell` say?
Comment 4 guimarcalsilva 2022-07-19 20:31:59 UTC
I noticed I can always trigger the bug by dragging the image from a Chromium based browser and moving the mouse fast over the panel, at the very edge of the screen. I also noticed in very rare cases it throws me back at the login screen instead of just making the screen go black.

Here's a video of the issue: https://youtu.be/eUAXeAv6qr4

The command shows 4 crashes yesterday:

Mon 2022-07-18 16:20:13 -03    2609  1000  1000  11 present   /usr/bin/plasmashell
Mon 2022-07-18 18:10:32 -03   16502  1000  1000  11 present   /usr/bin/plasmashell
Mon 2022-07-18 18:17:37 -03   21060  1000  1000  11 present   /usr/bin/plasmashell
Mon 2022-07-18 18:22:49 -03   22727  1000  1000  11 present   /usr/bin/plasmashell

Those are from yesterday. I think they're not related to this. I remember Plasma crashing when I was trying to diagnose the issue and I tried to run plasmashell with another command to pipe the terminal output to a file. I did that a few times, and that's when I think Plasma crashed (that's why I think it's unrelated). When the screen goes black no core dump is ever created. I'll add the crashes from yesterday in the next post, but I don't think they're related to this.

I got these using the new Dr. Konqi:
