Title: Something on ArcaOS 5.0 in Virtualbox
Post by: mauro on February 13, 2026, 01:12:12 pm
Hi, sorry if non joining Martin's topic talking about some Guest Additions weirdness in the latest VB version, I think not completely fitting for as follows:

-have Virtualbox 7.1.4 on Windows 11
-2 guest VM consisting in OS2 Warp 4.52 and ArcaOS 5.0
-both with Valery's GA 5.0.51 r218 , found best working years ago compared with te official Virtualbox ones, never tried other GA from there.

Have two things which could be improved.

1- ArcaOS 5.0 windows dragging shows annoying moving wake (video attached)
2- both VM leave "dirty tracks" when pointer touches upper or lower menu bar (image attached)

Do you think it could be caused by Guest Additions, or maybe video driver?

Thank you

Hello Mauro

1) Windows dragging. On my VM I still have something similar to your video.

2) About the "dirty tracks". I remember I used to have that long time ago. I think it got resolved by using a newer GENGRADD from the VirtualBox Addons.

Just as a personal note, I stopped using "Valery's GA 5.0.51 r218" when the official VBox starting shipping the VBox OS/2 Addons with WPS support for shared folders. But at this moment I recommend only version 7.2.4 and not upgrading the addons to 7.2.6.

Just in case, ArcaOS 5.1.1 comes with VBOX Addons and does an specific install procedure that had saved me time and works fine. 

Regards

Thank you Martin.
Can you tell -in case I'll try the GA 7.2.4 version-  if a proper uninstall job of the previuous installed (Valery's GA) must be applied ?  That is because I remember that it took a bit of manual installing work .

Hello

To disable Valery's Addons it just to REM those out of the config.sys.

Here it is the link of the older release just in case.
- https://download.virtualbox.org/virtualbox/7.2.4/VBoxGuestAdditions_7.2.4.iso

To install the Official VBOX addons, just take care to do not copy or replace some libc .dll that we already have in ArcaOS.
To do not confuse things, don't copy the Official Addons it on the same folder of Valery's Addons.

Regards
