Example cpp program showing the label size increasing
Description of problem:
Seen running wxPython program MAVProxy, original report is here
Example C++ program attached. On each OnTimer() the labels get a little bit wider.
Looking around with gdb and wxWidgets source, there is a dodgy increment in wxStaticText::DoGetBestSize() (stattext.cpp line 257). Removing the increment and rebuilding seems to fix the problem.
Version-Release number of selected component (if applicable):
Run attached wxWidgets example program.
Steps to Reproduce:
1. g++ $(wx-config-3.0 --cxxflags --libs) label-size.cpp
