thunderbird scroll bar width under fedora 14 kde plasma 6
the width of scroll bars in various places in thunderbird under fedora 41 kde plasma 6 is far too small. this is the only application i run where this is so. i can't seem to find any setting to increase their width. chatgpt provided no targeted solution. am i missing something? the scrollbars are so narrow that i can't use them.

There are a couple hidden settings affecting the resolution at which Thunderbird displays that may have an erroneous value. You may check whether that's the case and reset them to their default values as follows.
Go to Settings > General and click Config Editor at the bottom to open the Advanced Preferences tab, then repeat the following procedure with each of the following settings:
layout.css.dpi layout.css.devPixelsPerPx
1. Type the setting name (e.g. layout.css.dpi) into the search box of the Advanced Preferences tab.
2. If something has caused the setting to be changed from the default, a 'Reset' button with a counter-clockwise arrow will be available to the right of the 'Edit' button for the setting. Click that button to reset the setting to the default value. If no 'Reset' button appears, the setting already has the default value.
The Config Editor is documented here: https://support.mozilla.org/kb/config-editor
