Dear ParaView Community,
I’ve been trying to install and run ParaView on Ubuntu 22.04 (CPU-only system with Mesa/llvmpipe), but I consistently encounter the same issue:
When I launch ParaView, the window opens but remains completely blank and transparent — no splash screen, no menus, no render view. Just a transparent shell.
Here’s what I’ve tried:
```
Tested ParaView versions 5.12.1, 5.11.1, and 5.10
Used both the standard (GUI) builds and OSMesa headless builds
Installed and confirmed working Mesa (llvmpipe) with glxgears
Set the following environment variables:
```
export LIBGL\_ALWAYS\_SOFTWARE=1
export MESA\_GL\_VERSION\_OVERRIDE=3.3
export QT\_QPA\_PLATFORM=xcb
Verified OpenGL is working:
```
OpenGL renderer string: llvmpipe (LLVM 15.0.7, 256 bits)
```
Despite all this, the GUI still opens as a transparent/empty window.
Has anyone else encountered this? Is there a known workaround for CPU-only systems on Ubuntu 22.04?
Thanks in advance for any insights or suggestions.

Please test with ParaView 6.0 RC1 binary release from [https://www.paraview.org/download/](https://www.paraview.org/download/)

Thanks, but i already tried that too. I can only run the headless versions, without GUI. So i suspect it is the graphics.
I’ve tested the following:
```
ParaView versions: 5.8, 5.10, 5.11.1, 5.12.1, 6.0
Also tried Flatpak version
Confirmed that glxgears and glxinfo work
Forced software rendering with:
export LIBGL_ALWAYS_SOFTWARE=1
export MESA_GL_VERSION_OVERRIDE=3.3
export QT_QPA_PLATFORM=xcb
./paraview
Only the headless builds (OSMesa) work — I can use pvbatch and pvpython without issues
```
Hardware:
```
HP EliteBook 830 G7
Intel UHD Graphics (CML GT2)
OpenGL renderer string: llvmpipe (LLVM 15.0.7, 256 bits)
Running X11 (not Wayland)
```
At this point I suspect the issue is with Mesa or Intel graphics compatibility, as the GUI seems to fail silently when trying to initialize the OpenGL context.

Are you able to run ParaView 6.0 headless ?

Please run the following command and post the results here.
glxinfo
Then, try running glxgears. Does that work?

Dear Vivian,
just wanted to ask if you ever got it to work? I ran into the same issue, also under Ubuntu 22.04. If you happen to have a workaround, I would appreciate it if you could share it here!
Best,
Lina
