Flameshot is a screenshot program (installed through MCC -> Software Management -> Graphics -> Utilities) which I regularly used without problems in Mageia 8. After recently upgrading, I began to open Flameshot, at which point some kind of configuration warning was displayed. I neglected to make any record of the precise wording of this configuration message, but I am sure it was regarding configuration with respect to Flameshot.
Subsequent to that event, Flameshot does not work anymore and that warning has not appeared again. I have tried uninstalling then reinstalling this program, without any improvement. Would appreciate any assistance.
