Hi Jan! First, please try this patch which fixes a similar bug: https://patchwork.freedesktop.org/patch/78118/
If that doesn't fix the problem: I'd appreciate if you could upload the apitrace somewhere (Dropbox, Google Drive, etc.). A diff is not going to be useful.
But first, try if the problem is already fixed with the patch above :)
The patch works!
