I’m using Brave Browser Version 1.33.106, Chromium: 96.0.4664.110 (Official Build) (64-bit), on Ubuntu 20.04 LTS.
When I try to save a file, the file name in the dialog box is unreadable. It is written in a very light grey font on a white background, so there is not enough contrast to be able to read it. It is only when the file name is selected that it is readable.
Someone already raised this issue here, but it was not addressed by anyone.
