</div></div>try it, go ahead and revert<br>
a5f7c3e451b9fb643fb9d1e95819169394218082 (scale factor)<br>
or<br>
df90dec754e10e5c57246e1ad8f75550f559f8cb (high-dpi)<br>
(for example with<br>
git revert THE_HASH<br>
or<br>
git revert -n THE_HASH<br>
to just see if it works)<br>
<br>
I've seen the screen go blank, too (White, in my case) but resizing the<br>
window restored things, why so ever. However, I had it happen _before_ any<br>
of my changes, too. (But not with the CGView based backend, IIRC)<br></blockquote><div><br></div><div>Ah brilliant! Now I can wait until you fix it. Thanks, Tobias, the resize is great.
