Peter Hutterer <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] | |g --- Comment #9 from Peter Hutterer <[email protected]> --- ok, had a look through the recordings and they indeed show the same symptoms. in between normal-ish events there are events that cancel each other out. That's most pronounced in the last recording. This is related to the device being a semi-mt. Those devices only provide a bounding box and if you check the center of the bounding box you can see exactly those jumps: Touch 0: 0/222 Touch 1: 300/258 Bounding box: 0/222... 300/258 center: 150/240 Touch 0: 0/226 Touch 1: 300/254 Bounding box: 0/226... 300/254 center: 150/240 Touch 0: 0/231 Touch 1: 300/249 Bounding box: 0/231... 300/249 center: 150/240 Touch 0: 0/235 Touch 1: 300/245 Bounding box: 0/235... 300/245 center: 150/240 Touch 0: 0/239 Touch 1: 300/241 Bounding box: 0/239... 300/241 center: 150/240 Touch 0: 0/243 Touch 1: 300/237 Bounding box: 0/237... 300/243 center: 150/240 Touch 0: 0/247 Touch 1: 300/293 Bounding box: 0/247... 300/293 center: 150/270 Touch 0: 0/251 Touch 1: 300/289 Bounding box: 0/251... 300/289 center: 150/270 I honestly don't know how to fix this though. -- You are receiving this mail because: You are the assignee for the bug.
