Created attachment 115343 Journald output radeon ring 0 stalled for more than XXX msecs
Hi, when grading a video with the new GPU-accelerated kdenlive frameworks branch I encounter a GPU lockup when I add three effects to a clip simultaneously (White balance(GPU), Saturation(GPU) and Deconvolution sharpen(GPU) ) and seek the timeline. I already filed a bugreport here https://bugs.kde.org/show_bug.cgi?id=346184 but I think the problem lies in the driver rather than the program because trying the same on Intel hardware slows the system but there is no crash / lockup. Fortunately I managed to recover the journal (is attached) I hope you can help me. Thanks!
