Description:

The problem I'm experiencing is that when I press a key, the "KeyPress" event is not sent until the key is released, or ~200ms passes (my subjective timer, could be way off), whichever comes first. This problem only happens when I send input to a display which I've rotated using xrandr.

See: https://bbs.archlinux.org/viewtopic.php?pid=1687968#p1687968

Additional info:
* xorg-server 1.19.1-1


Steps to reproduce:

1. Rotate screen
2. Open 'xev' or just type in a terminal
This task depends upon

Please check/file an upstream report.

Did you manage to reproduce it? Any tips on downgrading?

By the way I filed a bug report here:

https://bugs.freedesktop.org/show_bug.cgi?id=99634

They/we think it's the Intel driver. Still no reproducers.

Is this still an issue?

You want me to change my config back and test it again? I just switched to the default driver which I think is modesetting. The upstream bug report has a latest post in November saying that the problem still exists on:

xf86-video-intel 2.99.917 (37a682aa)
xorg-server 1.19.5

I have xorg-server 1.19.6 but xf86-video-intel is still the same version 2.99.917. Do you think they would have fixed it without closing the upstream bug?

Since you seem to be the only Arch user you could confirm it still being present or fixed meanwhile on either Xorg, intel driver oder kernel drm side.

OK give me a day or two, thank you. I have many terminal windows open :)

I just confirmed that the bug is still present.

$ pacman -Q xf86-video-intel xorg-server
xf86-video-intel 1:2.99.917+812+g75795523-1
xorg-server 1.19.6+13+gd0d1a694f-1
