Machine Limits not showing in Linuxcnc 2.8.4

Hi,

I'm in the process switching from 2.7.x to 2.8.4 and encounered a weird issue. In the Preview window machine limits (Show Machine Limits) are not shown unless I toggle off 'Show Program' and 'Show Program Rapids'. Behaviour is the same in both Debian 10 Live booted from a USB and if I do a full installtion. I tested it on two PCs (one with dedicated Radeon card and one with built-in video) and the result is the same.
When booting back into 2.7.x the machine limits are properly shown regardles of other 'Show ...' toggles state.

Any ideas?

Thank you!
Dmitri

I googled a lot to see if anyone reported the same issue and could not find anything. Seems like I'm the only one with this issue.

I have this/similar problem on one test system using Mint.
I'll have to see if your 'work around' is the same.
