Caolán: should we consider it as a WONTFIX since gtk2 will be soon dropped?
(In reply to Julien Nabet from comment #2) > Caolán: should we consider it as a WONTFIX since gtk2 will be soon dropped? I believe we should fix gtk3 issues first before dropping gtk2.
(In reply to Julien Nabet from comment #2) > Caolán: should we consider it as a WONTFIX since gtk2 will be soon dropped? 6.3. release will have its life cycle for quite a while and leaving users with this bug is not humane )))
Could you please share a screenshot ? We already have these 2 reports -> bug 126791 and bug 125461
(In reply to Xisco Faulí from comment #5) > Could you please share a screenshot ? > We already have these 2 reports -> bug 126791 and bug 125461 I believe it is the same. I believe I used wrong keywords before posting a new bug. Recent document shows internal thumbnail.png, which is generated by LO.

(In reply to Xisco Faulí from comment #5) > Could you please share a screenshot ? > We already have these 2 reports -> bug 126791 and bug 125461 This happens only with gtk2 backend. It was introduced in 6.3 I believe. Earlier mentioned bug with black "About" screen was introduced at the same time.
Could you please paste the info from Help - about LibreOffice ?
(In reply to Xisco Faulí from comment #9) > Could you please paste the info from Help - about LibreOffice ? Version: 6.3.0.4 Build ID: 1:6.3.0-2~bpo10+1 CPU threads: 4; OS: Linux 4.19; UI render: default; VCL: gtk2; Locale: en-US (C.UTF-8); UI-Language: en-US Calc: threaded But it works in current 6.3.1 builds too.
So already fixed in 6.3 branch if prerelease 6.3.1 is ok?
(In reply to Julien Nabet from comment #11) > So already fixed in 6.3 branch if prerelease 6.3.1 is ok? No, it is not fixed. Only bug with black background of "About" dialog was fixed. Thumbnails in current 6.3.1 builds are black.
It seems I can't understand anything about this tracker. Uncc myself to avoid polluting.
