[06:08] <webchat47> anyone having problems with latest Slack on ubuntu 21.10 daily build?
[06:32] <guiverc> webchat47, https://bugs.launchpad.net/ubuntu/+source/slack/+bug/1943568 maybe - click "affects me too"
[06:35]  * guiverc meant click "affects me too" if the bug reports matches your issue... (sorry I wasn't clear)
[15:00] <Eickmeyer> guiverc: To be fair, I don't think slack is the problem. I've had the same symptoms with all electron-based apps in impish for the past week.
[15:00] <Eickmeyer> I'm trying to narrow-down the cause.
[19:48] <JanC> sounds like it's GPU-related ?
[19:51] <JanC> or maybe communication between the process that does the GPU rendering & some other process?
[19:53] <JanC> Eickmeyer: it might be useful to check if all people with this issue have nvidia non-free driver?
[19:54] <Eickmeyer> JanC: Yeah, that's what I'm working on. Unfortunately I noticed this on the 460 nvidia driver and the 470 nvidia driver. Seems to work when --no-sandbox is passed to the electron app, and it seems as though snaps and flatpaks are unaffected.
[19:55] <JanC> also, this bug report mentions a non-standard kernel also...
[19:55] <Eickmeyer> guiverc, JanC: I had to invalidate that bug, it's for the wrong "slack". We don't carry Slack in that reopos.
[19:55] <Eickmeyer> JanC: I'm using the standard kernel.
[19:55] <Eickmeyer> Long story short: ALL Electron apps are affected.
[19:56] <JanC> still, it would probably invalidate that bug report even if it was a supported package
[19:56] <Eickmeyer> Also tested Atom, VSCode, and Element.
[19:56] <Eickmeyer> JanC: Yes, it would.
[19:57] <JanC> https://xanmod.org/ kernel
[19:57] <Eickmeyer> One must pass --no-sandbox to get Atom and VSCode to work, Element seems to use a different Electron.
[19:57] <JanC> I suppose it's something for gamers & such
[19:57] <Eickmeyer> Yeah, idk.
[19:59] <Eickmeyer> I'm going to throw-out an email to ubuntu-devel@ to get some input. This only reared its head in the past week or so.
[19:59] <Eickmeyer> Probably two weeks ago.
[20:00] <JanC> might be useful to look at what build/runtime dependency packages were (significantly) changed recently
[20:01] <Eickmeyer> It would be runtime deps.
[20:20] <Eickmeyer> So far, everything is pointing at a gtk update from Sep 3rd.
