Hi, I’ve noticed that in versions starting from 5.0 in Linux (Ubuntu 22.04) the Add Data dialog box appears completely black the second time it is opened. I’ve tested it in 5.0, 5.2.1, 5.2.2 and 5.3 (preview). The first time it’s opened it works fine, but after closing and re-opening it doesn’t show…

Hmm, that’s odd. I mostly use Ubuntu 20.04 and have never seen that. Perhaps it’s a driver issue or something. Maybe someone else can comment if they have seen similar issues?

Thanks for you reply. I updated the NVIDIA drivers to the latest version (525) on my computer (GeForce GTX 1070) and still have the issue. I also tried it on three other computers (2 desktops with HD Graphics 630 and a laptop with Iris XE) with freshly installed Ubuntu 22.04 (I had to install libxcb…

That’s strange. I can have a look in my systems and get back to you (and eventually open an issue if I can reproduce this behavior).

I can’t reproduce this error on my Ubuntu 22.04 (nvidia drivers). I have tried both latest stable and preview (are you running on Wayland?). I would think the best candidate for this problem is a dependent package missing : Make sure you have all the dependencies required for Slicer installed ( Ge…

Thanks for the suggestions. All computers were on X11 but one. I’ve now realized that the issue appears only if the Add Data dialog box is closed using the “x” from the window. If I load some data or if I close it using “Cancel” it works fine. I have all dependencies and installing the development p…

You might also try building from source to see if this is an issue with the packages or something at the Qt or window manager level. You could also try different window manager environments to see if that makes a difference.

Hi all, I am having the same issue with both Slicer built from source and the official pre-built binary. I followed the first two steps mentioned by @RafaelPalomar here :- [image] RafaelPalomar: Make sure you have all the dependencies required for Slicer installed ( Getting Started — 3D Slicer…
