Hi - thanks for raising this. I've tried this on my stock Neon installation (plasma 6.0.2) and I repeat your test about 30 times and saw the issue once. So on my system (Thinkpad X390) it is very intermittent.

Are you able to re-try on 6.0.2 and report back? Also can you provide more details of your system and graphics card in case that might be a factor? Thanks Nick.

hi. yes, the bug can still be reproduced on 6.0.2. I also wanted to add that the bug occurs even on stock settings

distro - EndeavourOS, graphics card - AMD Radeon RX 470

OK - I can duplicate this now on Neon, but kind of the opposite of the original reported issue. If I change the desktop change animation from slide to fade, I can duplicate the problem (i.e. switch to a new workspace with windows already open, and then when I minimize / maximize by using the task bar buttons, the windows just appear and disappear with no animations). When I return to sing 'slide' the windows animate correctly.

Sounds like a reproducible bug to me so flagging this as confirmed hoping a dev can take a look.

Thanks, Nick.

I can reproduce this regardless of which desktop switching animation is used, as well as with it off. Also, restarting plasmashell fixes the issue until I switch the desktop again.
