Model: LG L Bello (LG D331)
Screen: 480x854 (196 ppi)
Android: 4.4.2 KitKat
Wikipedia app: latest version

When you view an article, then tap "X" to close it (and place it on the open tabs list), and then open it again from the open tabs list, the article text appears somewhat blurry (it's not fully sharp as usual). The problem is present in both standard, and Beta Wikipedia app.

Steps to reproduce the problem:

1. Open Wikipedia app.
2. View an article, the text is displayed perfectly sharp.
3. Tap "X" to close the article, and place it on the open tabs list.
4. Go to the open tabs list, and tap the article you just closed to view it again.
5. The text should appear somewhat blurry, not as perfectly sharp as before.

My Android phone doesn't have a high-definition screen, but this can hardly be the reason for the text to suddenly appear in lower quality. If you need any other information, feel free to contact me.
