Yes, I can reproduce with all themes. Even defaultxnview wrote:and with fusion theme?
1.Open XnviewMP, Maximize Window
2. Have preview panel in left bottom corner, Folder tree above Preview, Browser in Center, Info/Categories Along Right. "This May not matter but is my setup"
3. Enter a folder with Videos.
4. Enter a folder with pictures.
5. Go to full-screen, back to browser, back to full-screen.
Problem happens every 2nd time you enter full-screen, Main widget is seen along bottom and right hand side of screen cutting off picture.
To fix: Either switch themes or restart XnviewMP. "Stay out of video folders"
