First of remedies for the issue exists. For the LineageOS it is build in, for stock Android a third party app. Disabling the touch sensitivity of the outermost pixels. Very few android apps use extra slim scrollbars, that works less than optimal when the outermost pixel are not active.
To the question on how annoying the issue is, the answer is a little more complex. The first weeks I used the Pro1 it annoyed me while picking it up, slowly I adapted to handling it differently. Then I modified a Huawei P20 Pro flipcase for it, for protection. and since the problem has vanished completely.
