I just verified that my 'pharo-adjust-cursor' script does work for Pharo Launcher as well as Pharo images that are installed in a Linux Container on Chromebooks that have 4K displays (e.g., the "Pixelbook" models).
If you download the bash script from https://github.com/tbrunz/pharo-support/blob/master/src/pharo-adjust-cursor.sh to the directory that contains 'pharolauncher' and run it, it will update the 'pharo-launcher' script inside. Thereafter, when you run Pharo Launcher, or launch an image from Pharo Launcher, the cursor on 4K Chromebook displays will look normal size. -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
