which looks like https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/47/diffs?commit... to me. This upstream fix is shipped in xorg-server 1.20.4, a newer version than that in Leap 15.3 (1.20.3). I've put together a temporary fix at https://build.opensuse.org/package/show/home:yudaike:branches:SUSE:SLE-15-SP.... Would you please check if that makes any difference? Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
