I'm encountering an issue with my Wacom ExpressKey Remote having intermittent &quot;sticky&quot; keypresses. Truthfully I've had the issue for a while now but I'm tired of trying to figure it out myself and the issue has become worse since switching to Wayland. <br /> <br /> The issue primarily manifests when I use my Ctrl-Z undo hotkey within Krita (as that's what I use the most). I'll press it once and [i]something[/i] will think I'm holding the key down and act accordingly by undoing a bunch of actions. This will usually last until either realize it's happening and press a different key, or not relize it and make a stroke on the tablet itself losing all of those redo actions. Both are often after 10+ inputs' worth of undos. It's quite annoying. (It used to only be Ctrl that would &quot;stick&quot;, and would just be a mildly annoying color reselection. Since moving to Wayland, it's started repeating the Z part of the keybind and causing me to lose work.)<br /> <br /> And to be clear of what I mean by intermittent: it can happen three times in 20 minutes, or not at all in 2 hours. I can't identify any specific trend to it happening. <br /> <br /> Some quick system info:<br /> * KDE Plasma: 6<br /> * Krita: both the beta 6.0 from the Arch repos and the 5.3.x AppImages<br /> * Tablet (not that it's relevant): Wacom 27QHD<br /> <br /> <br /> Things I've tried that have not helped:<br /> * Using a different Remote device<br /> * Using a different USB receiver device<br /> * Using a different USB port (using one on my mobo instead of the one on the back of the tablet)<br /> * Using a different Remove with a different receiver plugged into a different USB port (while the original receiver was disconnected)<br /> * Closing Fcitx5<br /> * Disabling global hotkey repeat<br /> ** This one does *technically* work, but with the caveats that it seems to only last until I reboot (perhaps another bug) and that I don't really want to do this because having Ctrl-Z actually repeat undos is useful for me when I actually *want* it. <br /> * Binding the hotkey on the remote to the letter &quot;W&quot; so that it isn't trying to use a modifier key<br /> * Configuring the Remote button within Wayland to &quot;Defer to Application&quot; (doesn't seem to register anything within Krita)<br /> -------</div>

<p>Dracula: </p> <hr /> <div>== Good Facts to Know ==<br /> <br /> * If you'll lose 5 minutes of your time ''over your lifetime'' because you didn't know something, it's worth memorizing it with Anki. [https://gwern.net/spaced-repetition#how-much-to-add]<br /> <br /> == Card Design ==<br /> <br /> * Include context clues for cards. For example, I might have a card &quot;What does the PG provide?&quot; with an extra field called &quot;Context&quot; to display &quot;Ceph&quot; on the card. This helps because I can mix all of my decks together without getting topics from different subjects confused with one another. Having this as a field saves me from having to write &quot;...in the context of XYZ...&quot; to every question.<br /> * Do ''not'' include hints to the answer. If the hint is necessary, it should be part of the question and displayed by default.<br /> * Include a source field. Even if it isn't visible on the card, it's useful to have recorded in case you need to verify the information.<br /> <br /> == Misc Tips ==<br /> <br /> === Flags ===<br /> My personal approach to flags is this:<br /> <br /> * Red: Incorrect information, should be corrected immediately<br /> * Orange: Bad wording on a card or a card that can be split into multiple<br /> * Yellow: Bad formatting<br /> * Purple: Potentially unnecessary leech cards<br /> <br /> === Fix mpv Volume for Anki &lt;ref&gt;https://www.schoenitzer.de/blog/2021/Audio%20volume%20in%20Anki.html&lt;/ref&gt;===<br /> &lt;nowiki&gt;<br /> echo &quot;volume=80&quot; &gt; ~/.local/share/Anki2/mpv.conf<br /> &lt;/nowiki&gt;<br /> <br /> &lt;references /&gt;</div>
