This might help clarify/extend the backtracking in Blender versions
But the last one I used is 3.0

Hamdi Ozbayburtlu (hamdio) placed T98482: VSE: Wrap Width different between preview and render up for grabs.

I've debugged the text wrapping code flow and couldn't find anything wrong with width, height, size values coming into blf_font_wrap_apply from VSE point of view. And at first glance the wrapping calculation seems consistent. I reached out @Harley Acheson (harley) to understand the root cause. So the possible reason could be:

Wrapping code uses a measure of the string that should only ever overestimate by about the space between a pair of characters (because it includes the space after the last one) so is usually within a couple pixels of perfect.

Hamdi Ozbayburtlu (hamdio) claimed T98482: VSE: Wrap Width different between preview and render.

Yes, I can confirm the inconsistency. After debugging it, I see the preview window is doing the wrap calculation based on unscaled resolution while rendering uses the line width from scaled resolution.
So is it better to align preview to render flow and use scaled scene resolution for word wrap or the other way around?

Just a note, that this is not caused by rB7d1a10a9bbf3 - it was likely issue since first implementation of thumbnail drawing. It's likely, that before this commit thumbnails were not drawn unless you zoom in timeline a bit.

Peter Fog (tintwotin) added a comment to T70346: Render Animation: FFmpeg > DNxHD fail .

Well, having it fail without any useful explanation explanation, will be perceived as a bug by most users and it doesn't go well with the declared ambition of the VSE "should just work".

Hamdi Ozbayburtlu (hamdio) changed the status of T70346: Render Animation: FFmpeg > DNxHD fail from Archived to Resolved.

At the moment this information above is available if you turn on ffmpeg traces by launching blender with --debug-ffmpeg argument. So I'd say exposing it in a more user friendly way or making the ffmpeg integration project settings aware is an improvement rather than a bugfix.

Robert Guetzkow (rjg) added a comment to T99039: Python command gives indecipherable error (bpy.ops.sound.mixdown).

@Colin Basnett (cmbasnett) I've just looked at the code when I saw your comment and I fully agree. Given that AUD_mixdown and AUD_mixdown_per_channel are only used by sound_mixdown_exec, this change should be easy to implement. No other function seems to be using this incorrect exception handling.

Robert Guetzkow (rjg) added a comment to T99044: Blender instantly closes when clicking on the "Key" menu in dopesheet while drawing masks.

The issue is that graphop_editable_keyframes_poll (graph_utils.c) filters for animation data, iterates over the entries, treating all of them as FCurves. However, there can be entries that are no FCurves. Thus, the cast and subsequent operations result in the crash. In this particular case the creation of a mask results in an entry with ale->type set to 38 which is a ANIMTYPE_MASKLAYER. Skipping all entries in the loop that do not have an ale->type of ANIMTYPE_FCURVE seems to fix the issue.

Colin Basnett (cmbasnett) added a comment to T99039: Python command gives indecipherable error (bpy.ops.sound.mixdown).
