Is two finger scrolling really a high priority issue? It seems like a nice to have rather than a must-have IMHO.

On this issue, I'm not convinced that upstream can reproduce it, based on the comments in the ticket. I don't think that I've reproduced it either. Since you claim that it doesn't occur with wx 3.1, can you do a bisection between wx 3.0 and 3.1 to determine which commit fixed it? If we can figure that out, we can backport the patches.
If wxMaxima otherwise would be dropped from debian I am willing to switch to a flickering version that uses GTK3. But if I don't occur this risk I would rather stay at GTK3 until wxGTK 3.2 is released - which will fix this issue. The wxWidgets maintainers told me that wxGTK 3.2 will be released "soon". But the same was true a year ago - which I normally would be fine with: wxGTK 3.1 works fine, the combination of wxGTK 3.0 and GTK2 works fine, too - and it is wise to release a library when it is ready, not according to an arbitrary schedule.
Well, there is still time to fix the issues - Bullseye release is still a long way off.
And yes, upstream wx claims that wx 3.2 will be "soon" but we have heard that for a long time. :) So I don't think we can depend on that.
