[PATCH xserver 2/4 v5] xwayland: add a server sync before repeating keys

Key repeat is handled by the X server, but input events need to be processed and forwarded by the Wayland compositor first. Make sure the Wayland compositor is actually processing events, to avoid repeating keys in Xwayland while the Wayland compositor cannot deal with input events for whatever re

[PATCH xserver] glamor: Fix sampling outside of RGBx source/mask pictures

From: Michel Dänzer RENDER requires that sampling outside of any source/mask picture results in alpha == 0.0. The OpenGL border colour cannot set alpha = 0.0 if the texture format doesn't have an alpha channel, so we have to use the RepeatFix handling in that case. Also, only force alpha = 1.0

[PATCH xserver v3] xwayland: Use the CLOCK_MONOTONIC clock

By default the X server will try CLOCK_MONOTONIC_COARSE before CLOCK_MONOTONIC, while A Wayland compositor may only support getting their timestamps from the CLOCK_MONOTONIC clock. This causes various issues since it may happen that a timestamp from CLOCK_MONOTONIC retrieved before a sending an X r

[PATCH xserver 14/25] dix: Intermediate GrabServer state 'GrabKickout' not needed

The intermediate grabState, "GrabKickout", was used to trigger dispatch into going back to WaitForSomething after doing a GrabServer so that the set of ready clients would be recomputed to match what the server should be processing. As we only process one client per WaitForSomething call, we will a
