Capture2Text

What works

OCR capture, bubble capture and text-line capture with shortcuts when Capture2text (later - C2T) window is active, popup window with the OCRed text and it’s translation in it, live preview of the selected text, saving text and translation to clipboard, changing capture box colors. Icon of the program appears in the tray just like
in Windows and appears to be fully functional. Debug options (saving captured images and others) seem to be working.

What does not

OCR capture and bubble capture when C2T window is not active, left click capture confirmation and right click capture box drag when the cursor is not located on C2T window (clicking left or right mouse button on non-C2T window or pressing any shortcuts when no C2T window is active will apparently execute an action assigned to the button in the clicked window (e.g. clicking RigthMouseButton in a browser will open the menu, Ctrl+q will exit the application and LeftMouseButton will just make browser window active instead of confirming the capture))

Workarounds

For shortcuts to work you need to make C2T window active. Easy ways to do it: having the popup on top of all applications (e.g in KDE: RightClick on the border-More Actions-Keep Above Others) and clicking it before using shortcuts or\and setting a shortcut for activating the C2T popup window (e.g in KDE: RightClick on the border-More Actions-Set Window Shortcut) and pressing it before using C2T shortcut.

However, in order for the popup window to appear in the first place you have to RightClick the C2T icon in the tray and capture the text in the window that pops out (you also might have to Right-Click on that
popup, sometimes it doesn’t get active for some reason, like when you was working in a text editor before clicking the tray icon) and of course popup should be activated in the C2T settings.

Never use LeftMouseButton on non-C2T windows to confirm capture – use the shortcut you called
the capture box with for that, if you messed up you have to Left-Click on the C2T popup or tray
icon for the capture box to disappear. The same goes for dragging on non-C2T windows with Right-Click. If
you want to drag – start dragging from C2T window to wherever you want without stopping pushing RightMouseButton.

What was not tested

Text-to-speech (in windows you can choose Microsoft voices that are in Windows by default but obviously they’re absent in wine so you only have “disabled ” option in the settings. Maybe you can install voices manually but I’m not sure if it’d work and how you’d do it.)

Additional Comments

I feel like it’s probably possible to find some solution for most of the problems in Winetricks\Linux or with some Python\Autokey script but I don’t know any of those well enough. Overall I’m almost as efficient as on windows but the fact that you can’t drag properly makes it much less convenient sometimes so I guess it’s a silver for me.

Edit: After using it for several months I noticed a couple of bugs: 

1) It seems that bubble capture (and also maybe text-line capture, not sure) won't work on the bottom of the screen for some reason. I can't pinpoint the certain area, but it's somewhere around 1\3 at the bottom of the screen that doesn't work properly. (There's a possibility that's an application bug that's also present in windows, but I'm not sure, never really used bubble capture while on Windows). Standard OCR works fine at the bottom, so it's usually not a big problem.

2) Also sometimes text will randomly (doesn't seem like there's anything that triggers it) stop being copied into the clipboard, even
though it does get recognized and appears in the popup window. It might be an OS's problem though and not wine's. For me it gets fix by restarting the PC. (That doesn't happen very often, I've only had this twice, the first time I thought it was because of a wine update, but I guess it wasn't).
