Hi, I've checked vkmark and tried this locally and yes, this is a bug in primus_vk. I corrected it in the current master. The bug was triggered by the mailbox presentation mode that is selected by vkmark and is probably not that often selected by games and other applications. With the corrected version vkmark works on my system. Does it work for you now?

Works for me, thanks!
