If I choose another tab they become readable again. Reproducible: Always

I cannot reproduce. I notice that your screenshot shows you're not running the default theme - you have a the natively themed background for your tabstrip. What theme do you have installed?

I have not installed any theme. I use personal menu to hide menu buttons when they are not needed. They can be then shown by pressing alt. I use glasser addon for transparency. Disabling these addons doesn't help though.

I just noticed in the screen shot that you're running alpha 4 which has known bugs with glass. Can you reproduce this on a more recent build such as a nightly? There is hopefully another milestone release happening next week if you want to try a more stable build.

Reproducible on pre alpha 5 too.

(In reply to comment #5) > Reproducible on pre alpha 5 too. Sanity check: without Glasser, right? Can you give me a buildid? Go to Help -> About and copy that chunk of text below "License information" And could you also post steps to reproduce? Does it happen when the browser starts up? Does the window need to be maximized? Is fullscreen mode somehow involved?

Click on any menu button e.g. "tools" to open it. 2. Click on the button again to close it. 3. Result: tab names become unreadable until switching to another tab. I'll try updating minefield to the latest build and see if it helps.
