Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)

Exporting with H.264 High Profile preset with hardware encoder enabled and Codec quality set to 80% does not export Dither filters using the 6x6 90 Degree matrix. Video exports with Dither reverted to using 4x4 lines matrix. Both the filter, after export is successful, and the exported video confirm 4x4 lines matrix were reverted to.

Video playback in project file with dither 6x6 90 Degree matrix selected has no issues and plays smooth.
