Thank you so much Alistair! That worked for me! I actually already had a launch script for slack to do a bunch of stuff, one of the things is attaching an icon to it post-launch. I was able to modify the script to handle running the "xprop" line above automatically.
I'll post my script just in case it helps anyone, it's got comments so you can comment out sections you don't want. It does 3 things: 1. Launches slack with dev tools available (right-click inspect) 2. Applies the slack icon to the slack window after it's launched 3. Applies the window manager "NORMAL" type to the slack window after it's launched, so alt+tab works as normal. I launch using this script instead of the normal slack binary (I put it into ~/bin/slack and invoke it from there). ** Attachment added: "slack" https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1827302/+attachment/5261910/+files/slack -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827302 Title: 18.10 → 19.04 Alt-Tab cycling no longer includes Slack window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1827302/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
