Hi All, I've been seeing that issue pretty much since the first port from gtk2 to gtk3 (and now, as I recall, even in the gtk4 trial port). I've tried to build a small test case to reproduce it, packing a GtkTreeView in much the same way as in Balsa, but it never shows the issue. Some discussion in a possibly related issue[0] shows the complexity of tree-view rendering! I've actually not seen it in a while; each time that happens, I cross my fingers and hope that some minor tweak has fixed it, but it invariably pops up again :-( Peter [0] https://gitlab.gnome.org/GNOME/gtk/issues/485 On 02/28/2019 03:16:56 PM Thu, Jack via balsa-list wrote:

The point is: is there any (programmatic?) workaround?Hopefully I will have some time to dig into this a bit in the next weeks, but I suppose the next step would be to ask on a gtk mailing list/forum/IRC to see if it's a known issue at all. It's likely to be difficult to search for, as I can't think of any good search terms, although I have not yet tried very hard. In terms of workaround, I hadn't thought about different themes, but if you found it also affected other themes, then that doesn't seem a likely pursuit. Not seeing the problem in other applications using the same libraries suggests that it might be something in how Balsa does use those libraries, but that's not very specific or useful. If we're luck, then browsing the code might suggest someplace to put some debugging output, although I'm not very hopeful, as I suspect whatever the cause, the problem doesn't actually manifest until somewhere deep withing gtk. I suppose I could recompile gtk itself with full debugging info available, run under a debugger, and try interrupting the program when I see the problem. A lot of setup, but my best approach for now.
