RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

0001-backends-x11-wacom-pressure-curve-is-a-32-bit-proper.patch
Description of problem:
Changing the Wacom stylus tip pressure/eraser pressure changes the dconf setting but not the driver property so it ends up being a visually pleasing noop.
Version-Release number of selected component (if applicable):
mutter-3.26.2-7.el7.x86_64
How reproducible:
Steps to Reproduce:
1. xinput watch-props "Wacom Intuos Pro M Pen stylus"
2. control-center/devices/wacom: change slider for tip pressure
3. bring stylus into proximity of physical tablet
4. observe xinput watch-props output
Actual results:
Some properties change (tablet area, rotation, serial ids) but not the pressure values.
Expected results:
Something like:
Property 'Wacom Pressurecurve' changed.
Wacom Pressurecurve (301): 75, 0, 100, 25
Additional info:
Mutter expects a wrong property format, afaict the property has been 32 bits since around 2011 and has not changed, mutter expects it to be 8 bits. The mismatch causes change_property to never actually change the property (quietly...)
Patch is attached
