Comment 2 Tim Buschtoens CLA 2011-06-30 05:04:15 EDT 
Possibly the same issue or similar to Bug 340841.
Might also be connected to Bug 292189.
Comment 3 Ralf Sternberg CLA 2011-06-30 05:07:18 EDT 
The problem was reproducible even without browser zoom when we had a theming addition that changed the bold font to normal on hover. Strangle, it only appeared when pressing the TreeViewer button in the demo and hovering over the navigation buttons after this.
Comment 4 Tim Buschtoens CLA 2011-06-30 05:10:45 EDT 
There might be an explanation for that second scenario: TreeRow uses qx.ui.basic.Label._getMeasureNode(), just as MultiCellWidget/Button does. Perhaps something is done to that node that breaks textsize measuring.
Comment 5 Tim Buschtoens CLA 2011-07-05 12:38:06 EDT 
Fixed in CVS HEAD.

As suspected, these were two issues. One is the problem with textsize measurement not working anymore after a Tree appears. That was fixed by resetting the measurement Node properly. The other issue is about zooming an application. Thats actually the same bug as Bug 340841, and could be fixed in the same manner. 

What remains is the issue of zooming on runtime, i.e. after the application is already loaded. For that scenario i opend Bug 351218 - Improve support for browser-zooming on runtime.
