Hello @svan,
Code in previous post(s) generated the following errors on W10 with Processing 4.3:
This seemed to solve the problem most of the time but not all of the time:
frame.createBufferStrategy(2);
Above insight was gleaned from various references searching for:
createBufferStrategy(2) (or related)
and I am only sharing this as an initial exploration of this error.
:)
