YaST Development Report - Chapter 8 of 2022
Time for another development report from the YaST Team including, as usual, much more than only YaST.
[...]
Over the last year or so, we got some reports about the graphical interface of YaST presenting rendering issues, specially on HiDPI displays and on openQA. The reporters provided screenshots that showed how some widgets were apparently drawn on top of the previous ones without an intermediate cleanup, so the screen ended up displaying a mixture of old and new widgets that were very hard to read.
We were unable to reproduce the problem and we tried to involve people from different areas (like graphic drivers maintainers, virtualization experts or X11 developers) to track the problem down with no luck… until now! We finally found where the bug was hiding and hunted it down.
See the pull request that fixes the issue if you are interested in a technical description including faulty HiDPI detection, unexpected Qt behavior and QSS style sheets oddities. It also includes a screenshot of the described (and now fixed) problem.
