Allo,
I am running Firefox 89.0 and Kubuntu 20.10
Suddenly, Firefox's text looks blurry.
It isn't always blurry. When I move the mouse, it unblurs for 0.5 s. Even Firefox's menu text, like File, Edit Help are blurry.
Sometimes the window flashes black.
The text is way too blurry, to the point of like not having glasses on.
Brave's text looks slightly blurry but it is readable and doesn't change around when I move the mouse.
We shouldn't run a command without knowing what it does,,, tho to reverse what we did simply:
Code:
rm -rf .mozilla
(:that will remove the new settings folder automatically created by Firefox any time it's not found in home (because we renamed the original from .mozilla to the one now sitting in your home directory with no . )) then:
Code:
mv ~/mozilla .mozilla
that will reverse the first command I gave...
Code:
man mv
man rm
Then on to the next troubleshoots

Yes, like I said, I deleted the .mozilla folder.
I open Dolphin.
Make the invisible stuff visible.
Select .mozilla
Shift-Delete and click Yes.
Open Firefox.
I searched for mozilla in .config and .local but I couldn't find anything.
It's very difficult to find anything on the web. I tried duckduckgo and google.
Most pages were about Windows 10, Cleartype, some were about Chrome, one guy writes that Firefox's text look clearer compared to Chrome and Edge.
Man, I can't figure it out.
I am going to use another account.
I transferred some of the stuff from .config
and
.local
Is there a tool that can help copy a profile.
Some things, I can't copy. For example, Steam puts its games in .local/Steam and that is 200 GB. I would have to move it. Copying it takes too long and takes too much space.
Ondoho and web searches suggest that blurry text has to do with themes\looks\&c., do you set different themes up or has your distro?
For steam which is a whole nother question. In the settings I believe it allows you to set the preferred install folder you still may need to reinstall and delete or transfer them?
When I logged back into that problematic profile, looks like it got worst. Now, the desktop icon text sometimes looks blurry. Dolphin is effected as well, LibreOffice as well. The start menu as well.
Firefox has gone bonkers. Parts of Firefox client area looks slightly transparent. I don't use the compositor.
Linux uses something like the Windows GDI to do basic painting, right? Like draw lines, draw bitmaps.
I use what KDE calls global theme "Kubuntu". I changed it to Breeze but it did not help.
Possible solution.
I think the problem comes from the file that is in my home folder.
The file: .nvidia-settings-rc
If I delete it and log out and log in, the desktop icons look ok. Firefox looks ok.
If I restore that file and log in and log out, the problem comes back, specially with Firefox.
I do remember enabling FXAA via the nVidia console app.
Start -> Applications -> System -> nVidia X Server Settings
Is it possible that is what caused all this?
This is the bad file. Just after it, I have the good file from my new profile that I created a few days ago.
