Issue with ROOT graphics

[Andrea_Bellora]

ROOT Version: 6.26/10
Platform: Ubuntu 22.04.2 LTS installed as VM on Windows 10 Host (VirtualBox 7.0.6)

Since this morning (updated to VirtualBox 7.0-6) I’m having an issue in starting whatever ROOT UI.
No error message is printed out, however, when I open e.g. a TBrowser, it appears very broken (see below).

I installed the new VBox Guest Additions, but nothing really changed.
I also recompiled ROOT with no improvement
Do you have any suggestions?

Welcome to the ROOT forum

Yes, that’s weird. May be @bellenot has an idea.

Thank you @couet !
A quick update, I tried creating another VM with the same Ubuntu and ROOT version and the problem didn’t occur.
I also noticed that a similar artifact happens with glxgears (see below)

I’m not an expert in this graphics libraries, do you have suggestions on things that I should check/re-install? (xorg, GL libraries, etc.?)
Also, I don’t know if this information is of any use, but I have an intel graphics processor (no discrete GPU)

Th wrong image you posted firt is the GUI, that’s not graphics. @bellenot is our GUI expert.

My bad! Apologies!

[bellenot]

No idea what could be the issue, but if that happened right after the update of your Virtual Machine and if it works with another VM, then I would blame the VM itself…

Indeed,
I kept digging and found out that the issue was caused by the 3D acceleration option in VirtualBox. As of now, I haven’t found a way to get it to work again, but unticking that option solved all my issues.

Thanks!
