My computer broke, and while I am fixing it I have been running off a persistent Ubuntu 24.04 Live USB drive. I installed Kicad 9.01 and was able to open the projects I am working on. However, now the schematics open with black horizontal lines. All the components are there, just these annoying black lines. When I plot the schematics, the lines are not there. Any suggestions on how to remove these lines?
I’m not using V9 yet.
In previous versions there were setting to use accelerated graphic or not.
As I remember people asking here about some corrupted view changing this setting was what helped them.
First I’d upgrade to 9.0.3 and see if it’s a bug that’s been fixed.
Failing that under Preferences / Preferences / Schematic Editor / Display Options.
What is the rendering engine and grid display set to?
Mindful that you’re working off a Live USB drive, this has all the hallmarks of a GPU driver issue. Are you able to update to the latest for your hardware?
Also, what is the full KiCad version info?

Thanks to @gmc, I set the rendering engine to fallback, and it solved the problem.
When I get my new OS drive, and install Ubuntu 24.04, I should be set.
