Pier Luigi commented on NETBEANS-6039: -------------------------------------- I've just verified the same behaviour in NB 12.5 > Scrolling is choppy and laggy on Apple Mac Book Air M1 (at certain font size) > ----------------------------------------------------------------------------- > > Key: NETBEANS-6039 > URL: https://issues.apache.org/jira/browse/NETBEANS-6039 > Project: NetBeans > Issue Type: Bug > Affects Versions: 12.1, 12.2, 12.3, 12.4 > Environment: *roduct Version:* Apache NetBeans IDE 12.4 > *Java:* 11.0.11; OpenJDK 64-Bit Server VM 11.0.11+9-LTS > *Runtime:* OpenJDK Runtime Environment 11.0.11+9-LTS > *System:* Mac OS X version 11.6 running on aarch64; UTF-8; it_IT (nb) > *User directory:* /Users/picov/Library/Application Support/NetBeans/12.4 > *Cache directory:* /Users/picov/Library/Caches/NetBeans/12.4 > Reporter: Pier Luigi > Priority: Major > Labels: applesilicon, scrolling > > 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. > > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@netbeans.apache.org For additional commands, e-mail: commits-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
