I've noticed dragging objects has become very slow (the refresh rate is very low) in trunk.
I did a binary search and found the culprit is revision 15531 (Disable GTK3 "client side decorations" on Windows by setting "GTK_CSD=0").
Eduard, are you seeing this? Do you think it's fundamentally caused by disabling CSD or incidentally by some bug in GTK+?

Hi Yale,
yes, I noticed slow dragging in trunk, but didn't make the connection to "GTK_CSD=0" (thought it was a general gtk3 issue).
I hope it's not a fundamental issue, as it would mean we'd be unable to achieve an even remotely native look on Windows (that's the very reason why I set that option in the first place).
I'll check this evening if re-enabling client side decorations also resolves the other performance issues I'm seeing in trunk compared to 0.92.x and in any case I hope there's a possibility to get this fixed upstream.
Regards, Eduard
