Pier Luigi updated NETBEANS-6039:
---------------------------------
Description:
The scroll of source code is not smooth as it should be on a MacBook Air M1.
The keyboard navigation inside the source code using arrow keys is also laggy.
Changing version of Java does not affect this behaviour (tested with Azul Zulu
OpenJDK builds 1.8 and 11 for ARM 64bit (aarc-64).
Check the "Open in low resolution" option of the executable does not affect
this behaviour.
UPDATE:
I've discovered that the problem seems related to font size.
In my case I use "MS Reference Sans Serif" and the laggy scroll occurs if I set
the font size equals or greater than 15.
The behaviour seems related to font family: with San Francisco Mono the lag
start at size 17 or more, with Robot Mono at 14 or more.
On my Intel Mac the scroll is fast even at higher font size.
