1. Copy some text to clipboard.
2. Open via a) GUI app launcher menu or via b) terminal with just --verbose flag, open image, hit F2 to open rename field, paste text from a clipboard into xnview rename field, it pastes nothing. The same happen when trying to paste into the path/address field.
But when you switch Alt+Tab to a different application (maybe for couple of seconds, maybe no interaction with that app window is needed) and back to XnView, it now pastes the text from clipboard.
I have tried different image viewer (Gwenview) and it pastes the text on 1st attempt.
When I copy image content to clipboard using Edit > Copy to clipboard > Image content. The clipboarded image content can be pasted on 1st attempt into a newly created image (File, New image...), but when i quit and start XnView, it is no longer paste-able, but other app (Session messenger Appimage) is able to paste the image at this moment..
XnView --verbose output is here and some notable parts of it are:
...## MyDB::exec prepare failed (err=1): near "?": syntax error
query (first 200 chars): PRAGMA CACHE_SIZE=-?;
## MyDB::exec step failed (err=11): database disk image is malformed
Please could this issue be treated/fixed automatically for user so user will not face such issue in the future?############### UPDATE MENU ############

qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x582af50be7e0) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x582af53f01d0) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents
