IOC CubeIDE viewer doesn't render in Linux Mint

XR.1 · ‎2024-03-07

Sometimes it works, sometimes it doesn't.

When I try to open the IOC viewer either the IDE freezes or the view isn't rendered properly, as you can see below. This misbehavior breaks my working flow and makes me waste a lot of time. Any ideas?

I've met the issue as well, the solution is to use GPU to render the interface:

Right click on the STM32CubeIDE shortcut in apps menu -> Properties

Set "Use dedicated GPU if available" checkbox.

In my case the IOC interface started to render quick and reliable.

Hi! Thank you for the tip, but I guess it doesn't work for me that I'm using Linux Mint. I couldn't find an option inside Eclipse to enable the use of the GPU.

And ironically, today I haven't been able to use the IOC. It's been running for 20 minutes or so and it can't be rendered (100% CPU Java's usage):

This is a plugin's problem: after deleting some of them the IOC renders. There are sometimes when the full IDE refuses to start at all, and deleting the same plugins solves it.

Later on I'll write a tutorial on this issue. Meanwhile, the IOC windows looks like this (after I've lost a lot of time, Thank you ST :(
