Comment # 3 <https://bugs.freedesktop.org/show_bug.cgi?id=97549#c3>  on bug 97549 <https://bugs.freedesktop.org/show_bug.cgi?id=97549>  from  <mailto:michel at daenzer.net> Michel Dänzer 
Does the problem also occur with the modesetting driver instead of intel?



If yes, I'm afraid we can't make progress on this bug without seeing at least

the number of buffers used before and after my change in the affected cases,

preferably also the values of the variables used to decide that number.
