Comment 12 Fedora Blocker Bugs Application 2021-10-21 09:50:43 UTC 
Proposed as a Blocker for 35-final by Fedora user lbrabec using the blocker tracking app because:

 Testcase "QA:Testcase USB fmw" fails on Fedora 33.
Comment 13 Kamil Páral 2021-10-21 10:41:24 UTC 
It starts fine for me in a F33 VM, so this might really be graphical driver-related.
Comment 14 Lukas Brabec 2021-10-21 11:04:17 UTC 
Starts normally on Fedora 34 (bare metal, same machine where fmw segfaulted on F33).
Comment 15 Geraldo Simião 2021-10-21 11:26:46 UTC 
Starts normally here on a F33 vm too.
Comment 16 Lukas Brabec 2021-10-21 11:59:42 UTC 
Starts normally on fully updated Fedora 33 (bare metal, same machine where fmw segfaulted on clean installation of F33).
Comment 17 sumantro 2021-10-21 12:13:26 UTC 
Segfaults on  F33 1.2 RC but works fine on fully updated F33 and 34
Comment 18 Lukas Brabec 2021-10-21 12:14:13 UTC 
FMW seems to be working on fully updated Fedora 33, closing.
