Created attachment 183431 [details] Document with which the bug was observed I'm using Version: 7.4.1.2 / LibreOffice Community Build ID: 40(Build:2) CPU threads: 4; OS: Linux 5.19; UI render: default; VCL: qt5 (qfont+xcb) Locale: en-IL (en_IL); UI: en-US Debian package version: 1:7.4.1-1 to edit a document. Unfortunately, when I place the cursor on some of the paragraphs - it disappears. Editing works, but you don't see the cursor. In the whittled-down document I'm attaching I see this mostly on the last paragraph (which says חיפה, 6 בנובמבר 2022). When I had more content in the document, I saw it in other paragraphs, e.g. the one with אל תדאג אמר הדג.
Can reproduce with Version: 7.5.0.0.alpha1+ (X86_64) / LibreOffice Community Build ID: a611f2fc149153aabea8948f74ee004944acf681 CPU threads: 4; OS: Linux 6.0; UI render: default; VCL: qt5 (qfont+xcb) Locale: en-GB (en_GB.UTF-8); UI: en-US Calc: threaded but not Version: 7.5.0.0.alpha1+ (X86_64) / LibreOffice Community Build ID: a611f2fc149153aabea8948f74ee004944acf681 CPU threads: 4; OS: Linux 6.0; UI render: default; VCL: qt5 (cairo+xcb) Locale: en-GB (en_GB.UTF-8); UI: en-US Calc: threaded i.e. this appears to be specific to the qfont rendering code path that is not used by default with kf5.
