Bug: filenames become invisible sometimes

[thousandsofthem]

⚠️ This issue respects the following points: ⚠️

• This is a bug. Not a question or feature request.
• The topic is not already reported at Issues. (I've searched it).
• Markor is up to date. See Releases for the latest version. Updates are available from F-Droid and GitHub.
• The bug is still present in the latest development version (git master). (Please download and try the test version of Markor, named Marder. Don't worry; Markor and Marder appear as completely separate applications. You can install both side-by-side, and Markor settings are not touched. In case the issue is resolved there, you don't need to create a bug report. The change will be part of the next Markor update.)

Description

Sometimes list of files become like this:

After list of files breaks, it stays like this until force closing and restarting app. Any navigation works, but always displays list like this.

Steps to reproduce

1. Open list of files
2. Open some document
3. Navigate "back" to list of files

Sometimes list of files is broken after that, and remains so until complete force-stop of the app. Any and all navigation displays zero-length filenames

Sometimes it happens consistently 100/100, and after 30 minutes it never happens, 0/100 attempts. I don't know what exactly triggers the bug, but it's not orientation, screen size or exact .md file (happens with any file). Happens with .txt files as well, in root folder and subfolders. Can't say for sure about nightly build, need more time testing

UPD: can not reproduce on recent nightly build. It's either fixed or related to fresh start without any previous settings

[gsantner]

Probably it's automatic themeing, there are a few issues about that already. Can you please set Light or Dark theme fixed at settings where it not works?

Can you please set Light or Dark theme fixed at settings where it not works?

Fixed light theme - no issues on both stable and nightly (so far)

Fixed dark - there ARE issues on both stable and nightly
