Strange artifacts in panel text

Postby Metus on Thu Oct 18, 2012 8:45 pm

Hello,

I just installed Linux Mint Cinnamon and I noticed some artifacts in the panel texts, see pictures. I have no idea where they come from. Additional drivers says that no third-party software is needed for my graphics chip. How can I remove these artifacts?

I would start by taking a look at your fonts.
Maybe there's a way to "reset" your fonts in general.
Does changing fonts do anything?

I am not sure how to change the fonts in the menu. Changing the fonts in Cinnamon Preferences (not sure that this is the correct english term, I am using the german version) does not change anything in the panel.

I've noticed, that sometimes cinnamon doesn't apply changes on the fly.
Sometimes you need to reload cinnamon after changing settings.
Alt+F2 and run "r", try to change fonts and then reload.
Could also try
Code: Select all
sudo fc-cache -f -v
to rebuild font cache.
But tbh, it sounds like a gpu driver problem.
What card/drivers do you have?

Changing fonts and reloading does not fix the issue. Output from lspci yields

Same problem here, with Cinnamon on both LMDE and LM 14, same graphic card (X1250), "radeon" driver.

The first step should always be to let Cinnamon scale the panel.

Cinnamon Settings > Panel

I had some similar type artifacts back a couple months ago. Posted in the KDE subforum if you want to see my screenshot. End of January I think. Small white lines... was the title. Don't know what caused it or what cured it, but the system update did cure it. All those hundreds of update files.
