I haven't rebuilt Krita from 2.9ß since a bit before the holidays, and switching OpenGL off and back on with an image loaded in the editor works fine for me on OS X 10.9.5 with Intel HD3000 graphics.</p></pre>

The crash should either happen when switching off OpenGL or changing scaling mode.</p></pre>

Is there any reason to expect that your patch introduces a regression on other OSes (esp. OS X)? I won't have time to sync and rebuild Calligra for about a week.</p></pre>

This also fix the crash when switching scaling mode or anything that deletes a KisOpenGLCanvas2.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Changed the KisOpenGL API that deal with contexts a bit, now is possible to choose between switching on the shared context or a widget one.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">To avoid overhead switching on a context that is already current, i've added a check to see if the context we are trying to switch to is already current or not (the check doesn't use any gpu command).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This should make everything still work on all others cards and drivers, though it is better to be tested, so i put it here.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch is now present on branch origin/krita-testing-bonicatti.</p></pre>
