I will not have time to debug this for a few more weeks, probably, but here is something I found on the Web, could maybe be relevant:
https://github.com/tallforasmurf/CHIP8IDE/issues/22 TLDR: Somebody had a similar problem and fixed it by adding two QT calls after the QT Widget update() call. That was a few years ago, and possibly caused by a bug internal to QT. Neven -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel
