For me #define MAX_FLUSH_VERTICES 1 fixes the issue. #define
MAX_FLUSH_VERTICES 2 is also stable so far. Values starting from 3
result in artifacts.
However, as I wrote in post #150, reverting this:
diff --git a/src/sna/sna_glyphs.c b/src/sna/sna_glyphs.c
index 62415c8..43086a0 100644
--- a/src/sna/sna_glyphs.c
+++ b/src/sna/sna_glyphs.c
@@ -1130,8 +1130,7 @@ next_image:
- if (this_atlas->format == (format->depth << 24 |
format->format) &&
- (sna->kgem.gen >> 3) != 4) { /* XXX cache corruption? how?
*/
+ if (this_atlas->format == (format->depth << 24 |
format->format)) {
Solves the problem at all - even setting #define MAX_FLUSH_VERTICES 128
works correct, as well as #define FORCE_FLUSH 0 is also fine.
