--- Comment #38 from Benjamin Xiao <ben.r.x...@gmail.com> --- So it seems like if Kwin thinks that triple buffering is available then it causes "Painting blocks for vertical retrace" to be no. ------------------------------------------------------------- | KWIN_TRIPLE_BUFFER | Painting blocks for vertical retrace | |------------------------------------------------------------ | not set | no | |------------------------------------------------------------ | 1 | no | |------------------------------------------------------------ | 0 | yes | |------------------------------------------------------------ I am assuming that when it isn't set, the heuristics are detecting that triple buffering is available. After all, it is DRI3. -- You are receiving this mail because: You are watching all bug changes.
