I'm able to reproduce this issue only in Ubuntu Unity, not in Kubuntu, nor in Gnome. In Ubuntu 14.04 Unity, using the pen tablet to create a Multiline text, it triggers a flickering of the cursor, the toolbars, the status bar and the Tool Options box (see video below). Reproducible: Always Steps to Reproduce: 1. Drag a new multiline text. 2. Stay with the cursor over the canvas area. Actual Results: The cursor, toolbars, status bar and toolbox, start to flicker. Expected Results: Should not blink.

Tested on Krita 2.9 Beta 2 using an Intuos 4 pen tablet.
Yes -- with my intuos 3 I see almost the same thing, only not so fast. Somehow, the system keeps switching between brush and text tool.
+1 from me , this happens when we use tablet it is fine when used with mouse.
This also happens with the artistic text tool, btw.
We're working on a new text tool. The old text tool is now unmaintained and we won't be working on it anymore, so let's close all the text tool bugs.
