Confirmed issue here. Tested on Optiplex 3040, 3046, 3060. 2018 NUC. I get that some of these platforms weren't probably supposed to run Recalbox but wanted to exemplify the range of systems this issue exists on.
So this leads me to my next question. In general are fixes like this pushed via the built-in update mechanism?
On my working build I'm on the latest version before 6.0 was introduced. I've never seen an update come through the built-in updates.
I'm trying to weigh my options. (Install 6.0, roll with 6.1 and use the above workaround, use my old build and wait)
