Hi,
I'm currently testing the 2026.3.8.0 version, and encountered those bugs :
I Also encountered display refresh problems on opened RDP sessions (some abnormal squares appearing here and there, or only displaying part of the screen - see below)


Not exhaustive list. If I find others, I'll post again.

I'm on 2026.3.9.0 and am still experiencing the same issue.
Hello,
Which issue(s) do you still encounter? I am seeing 4 issues in your first post, so I am a little bit confuzed.
Sorry about that.
Best regards,
Jeff Dagenais
Hi,
So, I gave a try on 2026.3.9 which didn't solve any of the 4 issues I reported (Column display, display bugs).
Now I'm on 2026.3.10, and cannot yet reply for display bugs (just installed) but can already statut on column chooser, where issue remains :
This release : 
2026.1.14 : 
In this example, 1st column is now corresponding to "NECS Name' after having selected then sdeselected the "Host" column :

So, to summarize :
Thx.

Hello @oliviercammarata,
Thank you for following up and for the screenshots.
The missing first column header is a known issue, and a fix is in progress.
To view the full group names, right-click the column header and select Best Fit, or drag the column to make it wider.
I am also reporting your feedback that group names should use the entire row, as they did in 2026.1.
We reproduced the Name and Host issue in the Column Chooser, and I am reporting it to our development team.
Until this is fixed, selecting another folder and coming back will restore the columns.
Best regards,
Alexis Beauparlant
