Please describe your issue in as much detail as possible:

Even on the lowest graphics settings with a 1080 ti, the game stutters and generally feels bad on ubuntu 19.10. Using proprietary nvidia driver of course (latest from ubuntu)

Steps for reproducing this issue:

1. Install ubuntu 19.10 & dota
2. load bot game, pick underlord (hero doesn't really matter, but it's easy to reproduce with him)
3. spam firestorm-stop to freeze everything, longer the more you animation cancel.

I downgraded to ubuntu 18.04.3 (fresh install) and things are buttery now. Couldn't find anyone else talking about this so I opened a ticket.

System info is from working 18.04 install, but I didn't customize 19.10 at all, just installed it, installed steam, ran dota and was sad about performance. None of the nvidia driver customizations did anything

Most likely a GNOME 3.34 issue similar to https://github.com/ValveSoftware/Source-1-Games/issues/2875.

If at some point you switch back to Ubuntu 19.10, please check if any other desktop environment has the same issue.

Thanks Kisak, you guys are great. Thanks for supporting linux.

I'm probably gonna stick with 18.04 for now, and when 20.04 rolls around I'll try that. Hopefully I'm not the only one with this problem and it gets sorted, since I did like 19.10 otherwise.
