Blurred/fuzzy fonts

[rohrbrecher]

Describe the bug
As already mentioned in one of the user ratings I have the same problem with fuzzy fonts. I am using Windows 10 and a fresh install of Thunderbird 78.5.0 64bit. I installed the Theme right from the Thunderbird Addons.

Especially in bold text it is very blurry, I hope this is visible (see screenshot).

Screenshots

For comparison, a screenshot without theme:

Hi @rohrbrecher,
could you try this new version monterail-dark.zip? Is it better?

[rohrbrecher]

Hi, I'm afraid Firefox wont let me install it unless I use a Developer or Nightly Edition.

The plugin must be installed from Thunderbird "Tools->Addons->Gear icon->install addon from file"

Sorry but after installing it from zip it is still blurry. I also tried uninstalling first but same result. I might have to add that I am using a higher resolution (2560x1440).
