Hello,
The Linux version of Lunacy is very buggy.
It takes a while to open, and when it does, it freezes or there is a problem with the cursor
Hello!
I’ve asked about your OS and Lunacy versions in another thread, you may post them either here or in that thread. 
As for the cursor issue, is it this one? Mouse icon appears with a Fuzzy Box - Ubuntu 20 - #6 by samuelosoba
The problem still exists.
It takes several minutes to start Lunacy on Linux at high CPU load.
For now actually for v.9.0.9 and v.9.1.1 the startup doesn’t complete for a long time, well over 5 min. Total app freeze at very first launch, no UI, blank frame.
Nothing helps, so for me it is completely unusable on Linux.
I’m running hybrid graphics on my laptop: Intel + nVidia.
What is your OS version?
Pop!_OS 22.04
We’ve checked, and we have 63 users on Pop_OS. So far we haven’t received such reports from other people on this OS. For now you can try updating your drivers, especially for graphics. See if that changes anything.
Pop_OS actually is Ubuntu
You’re right, Pop_OS is based on Ubuntu. Having said that, other Pop_OS users have never reached out to us with that issue, so it’s a good idea to update your drivers first.
I tried different version of nVidia drivers, v.470 and v.525, but this issue has existed since the first versions of Lunacy I tried, that is to say at least since v.8
I have same problem, app freeze at first launch, os is Archlinux, and running hybrid graphics: Intel + Nvidia
I think you should refactor the code related to fonts:
I just tested v.9.2 and everything seems to be fine now, no hang-ups, app launches without freezing.
Looks like it fixed now!
Good job, thanks
