Only invalidate if the WindowPixmap changes
Flush writes to FakeFront on creation |
||
It does not happen on Pineview. Created attachment 58578 [details] [review] Only invalidate if the WindowPixmap changes But mesa can also squash this invalidation itself, the logic appears to be all there to spot the texture reuse. Hua, can you try the patch? And please retest with bug#44001 together. Created attachment 63854 [details] [review] Flush writes to FakeFront on creation Fails consistently now, without a compositor. *** Bug 47129 has been marked as a duplicate of this bug. *** Chris, do you need QA to test your patch? Seems to be working okay these days. Feel free to reopen if it still fails for you. Run 20 cycles, It works well. Close it. |
