In prefs.ini, there is a field name FontRecents, which contains a list of fonts and other data. Every time LightBurn exits, it re-saves prefs.init. When it does this, FontRecents grows. Eventually, prefs.init gets so large that LightBurn takes ages to start, like 2-15 minutes. If I then edit prefs.ini and delete all entries in FontRecents, the issue is temporarily resolved; until LB has been exited enough times to grow the field to be an issue again.
I do have a defaultprefs.ini if that makes a difference; we’re a Maker space so want to keep sane default settings. In the past I have removed the FontRecents entries from defaultprefs.ini too, just in case that was related to the underlying issue. However, the seem to come back there too; not sure if LightBurn re-writing defaultprefs.ini too, or whether some other member sometimes updates defaultprefs.init manually, e.g. by copying prefs.ini to it.
I have copies of all the prefs/defaultprefs files with/without this issue if you want; let me know where to upload/send them if you want them.
Thanks.
P.S. still missing Linux support… I was about to change our makerspace machines to Linux right when the announcement came out.
